ringing on a daily basis, no one talks when I pick up. I call back, it's an American female ansa phone WTF driving me mad!!

Claim to be Carphone Warehouse. Told me as I was in the renewal stages of my phone. I said 'No I'm not, I'm on a month to month contract' and he hung gup

I've had this number ring me several times over the past month, claiming to be Carphone warehouse and asking about updating my contract. Each time I've answered they've hung up when I've said I'm not interested. Doesn't seem legitimate.

Caller that called my mobile just now turns out to be the number above that is causing all the trouble. It rang off before I could answer but th at is the number that appears as my last missed call. So I went into the library to try and trace who it was as could have been something important that may not have had the number for previously. I will think about what to do next depending if any more calls come through on it.

Just had a call from these, he mentioned the name upgrade expert and carphone warehouse. He said my phone contract was coming to an end and as soon as he asked me to confirm my password I hung up

I've had two missed calls from this number today and after googling the number, it appears to be someone posing as the Carphone Warehouse. I didn't buy my phone from them so I know this must be a scam. Block this number!

This same company..........www.upgradeexperts.co.uk.......Are not to be trusted......They claim to be working on behalf of 02...........But 02 know nothing about them........Hang up if they call you !

I am getting several calls daily from this number - I do not answer now. V Annoying!

Call at least twice a day very annoying

This number called three times today. I am sick of this invasive behaviour. It has been on going now for several weeks. I have added this number to my reject list several times. O2 live chat most unhelpful regarding this subject. Any ideas how to totally block this number?

Its a London number rings at least 5 times a week

Claim to be carphone warehouse, offering free upgrade on O2, I'm on sim only contract so total rubbish. Told her wasn't interested and not to ring me again (every day this week), she said it wasn't her ringing me personally each time just the company and hung up. duh! Very rude, block number

I am getting phoned by this number at least 3 times a day I have told them to not use phone this number again and they constantly still do ... This is harassment phoning me at 8 o'clock  9 o'clock and 11 o clock  surely there is something u can do about this
