I keep getting calls from 020 3336 2954 and it comes up as suspected spam. They say they are from O2 and want me to confirm what email address they have for me. I ask them to tell me what address they have on record and I'll conform if it is correct but they won't. When I google search the number it does not come up as O2. Can anyone shed any light on this please? Thanks
Its a scammer pretending to be o2 to get you to give your personal data, which they will then use to defraud you.
Report the number to 7726
