Scam/Fraud
02 Dec 2025
Called by a serious sounding chap claiming to be from "Charing Cross Police Station". He addressed me by my surname and claimed they had someone in custody who had tried to use my bank cards. The conversation swiftly turned to "do you have a crypto wallet?". Strung him along for a while and then he abrubtly hung up before I could tell him to Foxtrot Oscar.

Indian man called and said he was from o2 and was offering new and loyal customers 40% off. I said I wasn’t on o2 and they hung up. Silly silly man.
