I'm pissed at Sky (UK broadband provider) because they started charging us for a service I never used and cannot use and never agreed to (Free Weekend Talk - I don't even have a non-mobile phone!) - it used to be free then all of a sudden it wasn't and there was an "opt out" and it was charged automatically by direct debit and my bank cannot help because (presumably) they "notified" me. It's a small amount (and thus harder to notice on the monthly bank account balance) but I wonder what would happen if they offered medical insurance (which, again, I don't need), first for free and then they changed it to £500/month and "notified" me (but usually I disregard these kinds of letters because they're not important, just spam).
Well, I'm really angry at my bank. I'm probably switching to one of the new, digital ones, either Monzo or Starling. Old incompetent banks are the best advertisement the newcomers could ever get.
