Just had a call from this number 'English Female' said she was from a company called 'CO2 save' asking if my name was 'Keith xxxxx' i answered 'yes' she said some one has reported my car having an accident ???

Keep getting calls from +8452251606 and 01512901677.  I am on T-Mobile.  I always ignore them but they still keep coming!!

I had my phone on silent and missed the call but from the sounds of it they sound suspicious. The question is where have they got my number from and are they connected with o2?

i have had numerous amounts of phone calls fro this number in the past week - i am on O2 but they just keep hanging up! i dont understand its getting annoying now. though id google the number... then you guys popped up!

today ive had 5 calls from these people!! they've rung me a total of 21 times since the 8th!! i never answer but its getting annoying!

I had a call from this number... I didn't answer because I didn't recognise it. Has anyone managed to find out who or what it is?

Calls me about 2-3 times a week. I've never answered. Not answering i case it charges.

ive been called by that number as well they asked about me if ive been in a accident i just said yes cant talk im at work im on o2 and on the registered on the site to stop spam phone calls so can i get them done.

I'm in the same boat as most of you guys - Mon to Friday, about 2 or 3 calls per day.
I don't answer but it's hugely annoying as I expect missed calls on my phone to be them now.
I have been in an accident a few months back but it was nothing major, just a scrape on the back bumper!
Oh well, I'm still not going to answer so they can waste their time ringing =)

I have been getting these phone calls about twice everyday. Never answer as i think i will get charged. Through reading the comments it doesn't sound worth it anyway. Anyone know how to stop them ringing?

Ive had the same 01512901677 number and )8452251606 number calling me twice a day all this week. I am an O2 customer also. I rang the landline number back and said i would like my number removed from the database. The lady apologised for any inconvenience and removed my number from the database. I don't know who they are or how they got it. its very annoying.

Like everyone I keep getting missed calls from the number, 2-3 times a weel minimum. Never answered as always at work, plus the dodgy number.
Called back by mistake today and got some weird music with a womans voice over the top, speaking something like chinese? WEIRD.
They are really starting to bug me. Like some other folks though, I had an accident a few months ago and my car was written off. Sounds like I might have a dodgy insurance compny who have sold me details on!

Ooooooh just to add, my insurance company was GoEco, and CO2 saving company.
I won't be re-newing with them!

Dodgy scouse guy asking for my husband, was on my mobile so don't get it?

i have been being called by them for about a week now. i finally answered it today it was a woman in india who knew my name and when i said what company is this she went quite so i sadi to her please take me off your records and put the phone down. not had a call back yet  but if i do i will be going mad.

I keep getting calls from this number and it is really annoying.  The few times i have answered the line just goes dead. I'm on T-mobile.

I'm on O2 as well! They call you asking if you've been in an accident. Sounds like they're dodgy as hell and I'm a lawyer anyway!!!

Had this number  +84 52251606 , the country code is I think Vieatnam ? I am a 02 customer.... not impressed what or who the hell it is but hope they burn in hell.

PS my car insurance is about to run out ? has someone sold all our number to some dodgy phone company?????!!!! AAAARRRRRRRRRRRR

Received 1st call from these people. They asked for Mr X but wasn't my name so I hung up. I'm on O2 also. The number, apparently, is a marker. You can somehow make your outgoing number say anything; go this case, a North American dial code.

had a missed call from this number this afternoon, thought is was a strange number..lucky i checked

Just had a call from it and they hung up as soon as I picked up.

I was called asked "Is that Stuart XXXXX" I answered yes, some giggling and then silence. I hung up.

got a call from +8452251606
answered, just hung up on me?

has called twice once last week
once this week, i answer they hang up?

Called once about a minute ago.  The hung up as soon as the phone was answered.

Called at 1332hrs GMT on 1 Jul 08.  I answered after 2 rings and the caller hung up as soon as I said 'hello'.

Just called me. Didn't answer, it'll be one of them where they charge you a lot when you answer?

had this twice in a month, never answered it as i didnt recognise the dial code

When I answered, they hung up on me.

Hi all, I missed a call from +8452251606 at 18:10 today to my O2 SIM card - I called the number back right away and got an error message on my phone that I've never had before: "Call Failed: Unassigned Number". I've never given my number to any dodgy companies so wondered if everyone else who's had calls from this number is with O2?...
