Telephone number: +443303035291
(03303035291, 00443303035291)

Keeps phoning,never leaves a message,same as its never going to get answered!!..Try leaving a voicemail,then we can choose!!......

Calls almost daily but I never answer. No message left so can't be too important !

How have they got my number , scaaaaaaaam ignore.

did not answer number unknown

Calls , but never leave a message. I never answer unless a message is being left Then I might pick up.

03303035291 tried calling my wife multiple times and she told them she was at work but the caller said he would phone later. My wife blocked the number. Later, she received a text thanking her for her purchase and to call 03303035291 if she wanted to discuss, or, 2220 to opt out from O2. The 2220 to opt out from O2 is correct but the 03303035291 number is a marketing company trying to get personal details and the 'purchase' was fictional.

Fed up always getting this number phoning.

Rang me 3 times in 3 hours today.....twice yesterday and several times on previous days but I didn't answer ...who is it ?

Someone called Charles asking me to confirm my name and address. Said he was from telephone preference service. Was my Visa card due to expire on 2018. When I said I didn't have a clue he became aggressive and said Go and get your Visa card and check it to which I Told him I Was ending the call and it was no business of his.

This number contacted me today 25/05/18. Reported and blocked now!!!!! Just a warning that it will happen to anyone else that tries Phishing or Spam calling! That is after they have been reported to Police Fraud Office. Very annoying and why should they get are our numbers. Data Protection Act is useless!!!!

please help me to stop this number 03303035291 from calling again and again

Unwelcome marketing

Sorry i meant 24/05/18. still the rest of the comment still applies.cheers!!!!!

I think this is O2. They sent a text telling me I was due an upgrade and they'd call me soon. Soon after this number called me but I was in a meeting so didn't answer.

call on my mobile,never leave a message,fed up with it

Stop these call fed up of them.arassment calls

This number keeps ringing me , sick to death of it,, 5 times Today

Called my mobile today(27/06/17) when I could not answer-but left no message.

Rings my mobile on a daily basis, even though I never answer!

please stop ringing me its a pain

Called today, Irish gentlemen, talked very quickly,reduced my 02 mobile bill by a fiver, genuine as I had a confirmation text from 02,and have spoke to 02 to confirm

First time they hung up. then second time i said hello 3 times before someone answered and said about o2 sales. i was at work so said couldnt talk. you cant phone them.... theyve rang me every day since for 4 days , got fed up so blocked them. frustrating . I will go and renew contract in MY time.

The calls from this number (033030352910) are from the O2 sales team trying to up sell you a new contract or phone.

Sick of this number ringing me,morning noon and night and never leaves a message or a text

01423229145 do not know who these are. Spam/scammers

several calls a day - becoming a pain in the butt.

Annoying. Phone was charging up. Son rushed to bring it for me. Only to find out it is anuisance call. So bloody annoying. Will block number. Princess

I also got calls from this number after a phone text from FromO2. Definitely a scam. Ignore and block

Calls at least twice a day. Never answer. Can't be important as they never leave a message. Who is it?

Over the last 3 weeks, on average 2 calls per day , today 13 November 3 calls so far, on my mobile,i do not answer a call unless i know who it is

They have been ringing me many times this week that last one was today at 10 past 6 in the evening. The caller said hello to me and then hung up so I have now blocked them. They should be reported to Off com for nuisance

Silent on answering. Nuisance.

I've been getting a call from this number everyday for the past 2 weeks. I finally answered and claimed they were from O2 and wanted to check I was getting the best deal. This doesn't sound like something O2 would do, so I shut the phone on them.

Same calls but no message. May be o2 as due an upgrade,

keep phoning me i never answer wish i could divert the call back on its self that would be fun thinking they were answering them selves

In all about 10 calls (did not answer) but answered the last call. Irish voice stating they were from 02 to deal with my contract. Told them not to call anymore. If from 02 why can't they do something about it. It is harassment!

Have just realised the call from this number which i missed came after a text message claiming to be from O2 saying I was due an upgrade and they would be in touch shortly. Dont think the text was genuine as `i don ot have a contract with 02 that would lead to an upgrade.

time waster do not pick up and delete..... if they had something real to say they would leave a message

Was from 02 so they said getting all facts wrong about my number then when I caught them out they hung up
