I was asleep but I can see they tried calling three times. It’s one benefit of growing old 😂

Said they were from sky and asked whether I had any issues with their service. It was the day I had connected and I was having issues but I told them it had been resolved. She then started talking about giving me credit so I put the phone down and blocked it.

Said they were from Sky. Asked me to guess a password I may have used in the past. Said they wanted to offer me a discount for bad signal. Got my email from me & then requested a new password code from Sky. I refused to guess a password, so they put the phone down on me. Obviously not Sky, as I logged in with my password & there was no credit. I think they wanted to access my direct debit & bank details. Very convincing.
