This number has called me 13 times over the last few months, including twice just today. It’s Zenith, and they’re such a hassle. I’ve never dealt with them myself but the last owner of my house put in Zenith windows, which are pretty poor quality. They don’t just keep ringing me, they also turn up uninvited at my house trying to hard sell. They’re seriously annoying and clearly desperate to push their products. I’ve blocked the number on my phone, but the calls still show up.

Zenith called me a while back. I paid them a lot for some work and honestly, it was rubbish. Don’t waste your time with these dodgy little lot, they’re just crooks trying to scam you.

Complete d*****ds. I blocked them ages ago and they still keep ringing. Who in their right mind keeps phoning a number only to get told they’re blocked? Just disappear already, Zenith, and stop wasting my time.

Got another caller ringing a mobile that’s not really used anymore, just kept on standby for emergencies. I never pick up and they don’t leave a voicemail, so I’m guessing it’s just another annoying spam call.

01603 574035 - This is Zenith. Just like others have said, I got windows fitted about 12 years ago but they keep ringing me every year, even after I told them to take me off their list. I've had 5 calls in the past couple of days alone - I'm just ignoring them now and blocking the number.

I didn’t catch her name, but she mentioned something about recycling. She said I’d signed up for something, which I’m sure I didn’t do. When I said I was renting, not the owner, she just hung up straight away.

I never pick up when this number rings, cos I've found out from this site it's Zenith windows. They keep phoning me even tho I only had some work done with them like seven years back. You'd imagine they’d stop hassling me by now.

Zenith Windows keep ringing me on both my landline and mobile, loads of times each day, despite me telling them to stop and to take my details off their list. I only dealt with them once, ages ago. They push really hard to make a sale. I think they first quoted something like £20,000, then after a week of back and forth, I ended up paying £1800. Honestly, avoid them - once they’ve had you, they’ll hassle you for ages afterwards.

Looks like from the other reviews this is yet another number linked to zenith. Luckily, ive got a call blocker that makes callers say who they are. Guess what? They never do, so the call gets blocked. They’re proper annoying, keep ringing even though i had some work done by them ages ago. It gets even worse cos i’ve got old family in norwich, so when i use 1471 and see the code i get proper worried in case something’s wrong.
