Strong accent just like other scam calls. offering 30% and 40% discount Sky discount. Asking about My Sky app. Keep asking for account information, email, password, names, bank information. They got upset when I said they are scammers and their numbers are marked as scam. We started swearing at each other. Quite entertaining.

They said they were from Sky and were offering a 40% discount. They had a lot of information about how much I was paying, the name on my bank account, the sort code and my address but then wanted bank details for security purposes. In particular they wanted the first 4 numbers of the bank account and got quite angry when I wouldn't give it to them. Very slick and very slippery.
