They kept the line open for about ten minutes without saying a single word, which seemed pretty dodgy to me.

I answered the call but there was nothing but silence, so I checked who it was and have decided to block the number now.

Nobody said a word, so I just stayed quiet too.

I spotted it was a dodgy number straight away and ignored the call. Saw someone mention this con has been active for four years now? Makes you wonder why the cops haven’t cracked down on these crooks yet.

I tried calling back but there was just silence, no one answered. The line didn’t even ring. I’ve gone ahead and blocked the number now.

Got calls from this number and a few slight variations, seems like the same scam operation to me. I've blocked them all now.
4 months
No message was left by them.

They didn’t leave any message on my answerphone. Pretty sure it’s one of those scam calls.

I saw the reviews and decided not to pick up, quite glad I didn’t bother.

I got a call from 01204213521 but didn't know who it was and they didn’t leave any message. So I just blocked the number - seemed pointless and like it could be dodgy. Wasted my time, so best to just ignore it.

Got a random spam call from this number, didn’t pick up as I wasn’t sure if it was safe. I’ve gone ahead and blocked it now and flagged it as 'Harassing'. Better safe than sorry!

Got a call at 3:38 pm but it went straight to voicemail. No one left a message though. I just blocked the number, probably just another annoying spam call.
4 months
No message given and it feels like a scam to me. Not sure what to make of it.
4 months
They hung up the moment the voicemail started, no way a person can react that quick, must have been one of those automated calls.
4 months
I said hello and then they just shut the call off without saying a word. These kinds of calls, if there’s no real reason for them, ought to be illegal. Honestly, it’s mad how this kind of harassment is still allowed in today’s world!
4 months
I got two calls today from nearly the same number, only the last digit was different, like 01204213526, the second one coming about six hours after the first. From what I've read in other comments, this is just the usual energy company scam crew who have been pestering us for over four years now. Their main goal is to get personal info, especially to find out if you own your home. They’ve got zero genuine offers or anything useful to say.
4 months
Got a call from someone claiming to be my local energy advisor. I asked why the number didn’t look local and he just said “oh, alright, goodbye” and hung up. I probably shouldn’t have picked up but I was expecting another call so thought I’d just quickly answer it. Anyway, I’ve blocked the number now.
4 months
It rings at the exact same time every day, but I just ignore it now.
