Scam/Fraud
19 Dec 2025

They said they were Sky, my mobile SIM would stop working in 3 days due to bad interference and were going to send me a new 5G SIM. Asked me for my email address to progress order. I refused and said I would clarify with Sky to check. He the got stroppy and said I was wasting his time, I said he was wasting mine and put phone down. I did ring Sky and after alot of investigation by them they confirmed it was a scam. Very convincing at beginning of call so don't be taken in.
