got a call @7.37 pm. missed it, tried to call back but "number error".... which is probably better, it would probably charge quite a lot for a call to Vietnam. If anyone has any more explanation that what has already been said in thjis topic please let me know. i am on O2

Same number to me earlier tonight. I'm on O2.

Got a call from +8435400007 at 7pm tonight. Was out thankfully so missed the call and yes like most other people I'm on O2.

missed a call from this no too

I got a call today and they hung up, on my Land line which is Talk Talk, I am on 02 so will look forward to receiving one on that phone too, what fun!!!!!!!!

I got a call last night 19:32. Did not answer and funny enough, I am on 02. I have a company phone and not personal phone but still, make you wonder why 99% of people are on 02. Is thos how they now make their money. I also launched an official complaint with O2 and informed BBC Watchdog. Suggest all do the same

I'm also on o2 and got a call from this number last night after 7pm. Considering there are only recent problems with this number, and mostly on o2 and all of the calls are done late - it must be scam. If it was truly important, they would have left a vm...

I just got call and answered no answer. Has anyone else ever gone through phones for you and got insurance ? I have never gave out number or had any bother before they offered me free insurance when upgraded I have a feeling that they have passed number on to these company

i got a call from this number just a few minutes ago and as this has never happened before i answered it.  luckily, they hang up on me because it sounds like the call would've cost me money!  i can't believe that it seems to be mainly O2 customers complaining as i'm on the same network.  i'll definitely be more careful.

I got the same number calling me and i am on 02, hope this stops as its annoying i never answered it

i keep getting calls from this number to, who or wot the hell is it?????????

called my phone at 19:13 tonight, i ignored it as unusual number dialing code appears to be Vietnam, and yes i on O2 as well, are they allowed to sell our numbers like this?

I just had a call from these cheeky b******s at 7.20pm!!!!! rejected it straight away,its so obvious its a scam!!!!!!!

They shudn't be aloud to give our numbers to anyone, i've just another call from the number, i tried calling it bacj and just got wrong number displayed on phone. yeah im o2 aswell. this is becoming a joke now.

I got a call from this number but never answered it,is it dodgy??

Just got a call and was told please do not drop- this is a public msg.... yada yadda
The only reason I picked was because I have a lot of calls from abroad. I was formerly  on o2 butt ported my number to vodafone so I guess o2 has some questions to answer. If i get charged, I'm claiming my money back!

Just rang O2 to ask about this number, after taking the number from me he kept me on hold a while, then said that number wasn't known to them ????? he then tried to say i must have given my number to someone, like entering a competition, i said it only seems to be O2 customers.  No joy from O2 !!! :(

Only advice he gave was, Don't answer it !!!!

Missed a call at 7.31 just, who are they? I'm on 02!!!

Hi fellow O2 Mobile phone colleagues...

Looks as if ALL O2 Mobiles received a call after 7pm this evening and yesterday at same time -
It feels like a SCAM but why? Think Martin Lewis and Watchdog should look into this for us.

It's not on that a big company like O2 can let this sort of thing happen.

WE DEMAND ANSWER...NOW!!!!!! OTHERWISE WILL TAKE ACTION IF ANYTHING ELSE HAPPENS AS A RESULT OF THIS.

Also got another call from them about 30 minutes ago. Last time(2 days ago) I answered and hung up after 13 seconds, but this time I ignored. What is their game? Also on 02, but cant get my head round how they make money if they keep phoning from Vietnam and either we answer and hang up or ignore. There has to be a scam involved but what??????

PS...WATCHDOG IS ON BBC1 TONIGHT @ 8pm!!!

Had a call last night and again tonight at the same time 19:34... Didn't answer either time. Hope that no one else gets charged or scammed from answering the call.... Gonna report it to O2 tomorrow if it rings again....

to a** too ReedL1's post and to highlight this issue email - watchdog@bbc.co.uk

add not a**

I just had the same thing and...............yes, i am on O2. Oh dear oh dear! what have they done!!W7T4

i just had a call from this comptny too, answered it and they hung up.

I rec'd a call from +8435400007.  I am a T-Mobile customer.  Did not answer the call, but would like to know how they got my number.

I had a call too. ignored. I'm on T-mobile.

I too had a missed call from this number a few minutes ago......I am on the Virgin network,do not give my number out,or enter into market research or surveys.....The debt that I have is being paid as it should on time etc....

To be honest,I am frequently getting unsolicited calls from all manner of debt management type companies,who all insist I have filled out forms requesting help from the like......NO,I HAVE NOT!!!!

Every time a number that I am not familiar with rings now,I let it ring.......if it is a bona fide call,they will leave a voice mail message......I suggest You all do too...it will save You the angst..
