Scam/Fraud
09 Sep 2025
Claims I have a contract with Three (mobile phone provider) — I do not. (I used their pay-as-you-go some 10 years ago before they tripled their prices. I never had a phone contract and money leaving my account would be bloody obvious, — l am not a multimillionaire!) So I told them that was news to me. “I am telling you right now you have a contract with Three…” Asked for the contract number. Got the last 3 digits of my phone number. Which they just called, a top secret number. I repeated I wanted the CONTRACT number. Hang-up.
