I've taken to letting all unfamiliar numbers head straight to voicemail. I've got a little message set up that says, "I don’t pick up calls from numbers I don’t recognise. Please leave a message, and I might return your call."

For the past couple of days, I've received calls from this number, and upon spotting the 0800 dialling code, I chose to ignore it.

I received a call from an individual claiming to represent 02, attempting to entice me with a so-called superior plan. When I politely declined, he proceeded to suggest an improved family plan instead. I turned that down as well, yet he audaciously inquired if I was absolutely certain about my decision!

An absolute nuisance!

I chose not to pick up as I didn’t recognise the number, and they didn’t bother to leave a voicemail either!

Received a call from an unknown number that feels a bit dodgy – likely spam, I reckon.

Fraudulent activity detected!

I receive around three calls each day—once in the morning, again in the afternoon, and the last one in the evening. Strangely enough, none of them ever gets answered. I’ve done some digging and even consulted a few friends, and it appears the number might be linked to O2, although I'm rather sceptical given that they don't leave any voicemails.

They've been ringing me three times a week!

I've received a couple of calls from this number now, but they haven't bothered to leave a message or a voicemail. I can't help but think it's a scammer on the line.

I put a stop to that number last year, yet they persist in ringing me daily without fail.

They've called pretending to be from O2, but I’ve checked with O2 themselves, and it turns out that this isn't one of their official numbers. Quite dodgy if you ask me!

I got a rather peculiar automated call claiming I was the sole attendee on some kind of conference call! Naturally, I put the phone down straight away. A few minutes later, they tried again, but I chose not to pick up this time and promptly blocked the number.

Received a call from O2, where they provided me with some fundamental details regarding my account, such as my name, number, and monthly fee. They were keen to up my data plan while slashing the price, yet insisted I sit through a lengthy explanation of the terms and conditions. I decided it was best to end the call.

It seems like I've been plagued by these dodgy characters, as they've rung me several times throughout January. Honestly, I hope they find their way someday!

I've had several calls from this number, purporting to be from O2, saying they could help me cut down my bills. I asked them to take me off their calling list and to stop ringing me, but they just kept pestering me on my mobile. I've had enough and blocked them now. I'm quite sure these are dodgy characters trying their luck.

I received a call from someone purporting to be my mobile provider. They began with, "Hello, it's your network provider," to which I asked for the name of the network. Suddenly, they cut the line. Very peculiar indeed!

Utterly irritating! I've really no desire to engage with these individuals at all.

Over the past week, I've received a number of calls from individuals purporting to be from O2, my mobile network. I was suspicious right from the start, so I decided not to engage. However, today I picked up the phone, and they inquired about my devices. I couldn’t help but reply, "Surely you would have that information on record?" The conversation didn't carry on for long after that!

Called me but hung up in a jiffy. I didn't recognise the number, so I chose not to pick up. Seems like it could be just another pesky, unsolicited call.

I wasn’t familiar with the phone number, so I decided to look it up on 'Who Called Me UK.' Turns out, it’s linked to telemarketing and Virgin, along with a few others. Interestingly, they didn’t bother to leave a voicemail. I’ve since blocked the number on my mobile.

Received a call from a bloke claiming to be from O2. He enquired about my satisfaction with my phone and whether I had any thoughts on upgrading. I told him I was perfectly content and had no intentions of changing my device. He replied with a brief "okay, thank you" and promptly disconnected the line.

This number is simply unbearable! I've included it on my Blocked list, yet I still get notifications from Truecaller about their incessant calls. They managed to try ringing me twice yesterday and once this morning already. They've been at it for three consecutive days, pestering me once each day in September. I've no idea who’s behind it, but I’m determined to keep it firmly blocked!

This number has been giving me a bell a few times each week. I’ve decided to block it, especially since I've come across some online information suggesting it might be a scam of sorts. Best to err on the side of caution, I suppose!

Received a call from this number claiming to be from O2, stating there was an issue with my account. Oddly, the caller abruptly ended the conversation, leaving her words unfinished! Quite peculiar, I must say!

Over the past three days, my phone’s been buzzing with a staggering 12 calls at all sorts of hours, from the crack of dawn to the dead of night. I’ve chosen not to pick up, and oddly enough, not a single voicemail has come through. If these were legitimate callers, surely they would’ve bothered to leave a message, don’t you think?

I've received countless calls from O2, despite having reached out to them to request that they cease their marketing phone calls. It's getting quite frustrating!

I've received a scam call purporting to be from O2. When I confronted the individual on the line, they abruptly cut the conversation short and hung up.

Claimed to be from O2 and had some info for me, but unfortunately, the call dropped.

I've received a staggering nine calls from this number! I've actually picked up twice just to explain that I'm quite satisfied with my O2 plan and have no interest in switching. They've got all my details from O2, which makes it seem legitimate, but despite my clear disinterest, they continue to ring me. I've finally had enough and decided to block the number. Quite exhausting, really!

I received a call from someone purporting to be from O2, and they had the gift of the gab, making it sound quite authentic. However, when I tossed out a fictitious price from a rival company, they claimed they could match it. It all seemed a bit fishy and downright unlikely, if you ask me. It definitely had the hallmarks of a scam. I ended the conversation and promptly blocked the number.

I let it ring out. I never pick up calls from numbers I don’t recognise. It’s a sound piece of advice that I reckon everyone ought to take heed of.

Rang me thrice consecutively, but since I’ve only just got this new SIM, I decided to leave it unanswered.

I received a call whilst I was at school, but didn’t pick up, hence the number remains a mystery to me.

Picked up the call but there was silence on the other end. After a moment, I decided to hang up and check the number. Upon seeing the feedback left by others, I promptly blocked it. Cheers for the heads-up, everyone! 👍🏻

Nefarious characters and con artists. I've given them the boot 🚫🚫. Also flagged their number. Just received an unwanted call!

Fraudulent callers, utter nuisances! I've had enough and have now blocked them 🚫🚫. I've also made sure to report their dubious antics. They shouldn't be ringing people out of the blue!

I've received three calls from this number now, claiming to be from O2 advisors. They keep insisting they want to discuss O2 as our internet provider, but here's the thing – O2 isn't even our internet provider! Just a friendly heads up: watch out for 08009524854!

Received a call from this number but no voicemail was left. It's clear this is likely a dodgy operation.

Feel free to give me a ring as often as you like; I won’t be picking up!

Cheers for that! I avoided picking up since I suspected it might be a non-local number. However, the details you’ve shared are incredibly helpful.

Received a call purporting to be from o2, claiming they wished to conduct an annual review of my account. I decided to end the call.

Receiving daily calls from this number. Have now added it to my blocked contacts.

I've received a few calls from this number, and it's definitely a scam.

Received a couple of calls from this number, once in the morning and again later in the day. Haven't had any other messages or notifications from O2 at all. The number was 0800 952 4854.

I’m a bit puzzled about whether this is a scam or not. They simply enquired if I was satisfied with my phone and contract, nothing more. They already seemed to know my name and the details of my contract, then just said thank you and hung up. Strangely, they didn’t attempt to offer any discounts or ask for any personal information like my address or card details. Quite baffling, really!

I received a couple of calls from 08009524854 today, but I opted not to pick up. I’m left wondering if this could be yet another dodgy scam. I’m quite curious about their intentions, seeing as I didn’t engage with them.

Rang me four times within a couple of days—I've since added the number to my blocked list.

I received a call from 02 yesterday as well. I can't shake the feeling that it's not genuine and might be a scam.

I received a phone call from someone claiming to represent O2, who was keen to discuss upgrading my current contract.

I missed the call, but after reading other reviews suggesting it's linked to O2, it all clicks into place. Just recently, only about an hour back, I renewed my phone contract with them. So, I reckon this call could be related to that.

I received a call from the number 0800 952 4854 at precisely 10:46 this morning. I picked up, but oddly, the other party didn’t utter a single word before hanging up. Quite strange, really!

Received two calls from this number today – one at twenty past ten and another at five past three.

I received a call from a woman with an Asian accent saying she was representing O2, but she only wanted to communicate via email. After a brief chat, she just hung up on me. Quite peculiar!

They called, pretending to be from O2, saying they had a brilliant offer for loyal patrons. However, when I mentioned I was too busy to chat, their attitude took a nosedive and they became quite impolite.

They claim to be from a healthcare organisation and are seeking participants for a survey.

I received a call from a bloke who sounded Irish. He mentioned my name and inquired about whether I was considering updating my phone. I told him I was all good and hung up.

I’ve been unable to unearth the identity of the person behind these calls. I've taken to ignoring any number that doesn’t ring a bell on my phone. Nevertheless, they’ve tried getting in touch with me on two occasions. It looks like they prefer Wednesdays around half five in the afternoon to make their attempts.

Got a ring from 0800 952 4854, saying they were from O2 and that I could take advantage of some offers. They requested my full name, but I pointed out that if they were genuinely O2, they should already have that information on their system, and I wasn't willing to share it over the phone. The caller replied with a friendly 'Alright' and hung up. The voice had a nice northern English twang to it, quite pleasant, really!

The call disconnected the moment I picked up.

Received a call claiming to be from O2, discussing the possibility of switching to a more economical plan since my current one is rather costly. They also mentioned something about upgrading my phone. They seemed well-informed about when my contract began and the model of my device.

Received a call purporting to be from O2, and I must say, I wasn't thrilled with the way he directed me to their website during our chat. It felt rather peculiar, plus there was this cryptic access code involved. In summary, it all seems a bit dodgy to me.

Claiming to represent O2, they are.
