Suspected scam calls

[JCH49]

Hello.

I keep getting telephone calls to my mobile claiming to be from O2 and offering me discounts on my bill.  When I ask for confirmation that the calls are from O2 by asking for my postcode I and told that they cannot do so until I have responded to a text message that will be sent to me.

Are theses genuine calls, please?

[Enlli · Accepted solution]

No. And that text will contain a One Time Passcode. Give that code to them and they have access to your account.
