A Private phone ringing me .. is it O2

[monkeyspunk]

I keep get a private number ringing me saying its O2 and they can half my bill ... Its a Indian call centre and half way through they say I don't have to contact or tell Virgin or O2 .. It all sounds very dodgy and I hang up .. Do O2 have Indian call centres working for them ? .. Does this sound legit ?

It's a well known scam
Don’t give them any information. If the number has been withheld you can't block it so just hang up.

Just had this call today, I questioned why they were calling me from a private number and it wasn't appearing as O2 on my phone, the response I got was so ridiculous, that their phone lines are so busy and they have to use an alternative line. The hilarious thing is they think you actually swallow it. I told them to send me all the details by email then hung up. Surprise surprise nothing came in. In 20 years O2 have never called me to upsell me any product or save me money.

But bear in mind that even if your handset says that it is O2, it doesn't mean that it is - "number spoofing" will make it appear that O2 are calling you when it is a scammer. 

If you are in any doubt, terminate the call, reboot your handset and then 'phone O2 on a number that is on their website.
