Insurance companies
So I've been with this insurance company for my home and contents since 2004. I call to cancel as I've decided they're way too expensive.
Every year it's just rolled over without me having to contact them so I figure I'd like an email confirmation of the cancellation so it doesn't just roll over again. Guess what? They can't oblige and I just have to rely on a verbal confirmation.
What's the bet it rolls over, I call them and they have no idea what I'm talking about. Fuckers!
