Web page hosting?

I've had great host providers that offered everything I needed for a good price, but then when something went wrong there was nobody around to help me. One in particular I can remember moved everything to a new server and then 2 of my domains just wouldn't work. I tried everything!! Nobody would answer emails, nobody anwers the phone..finally I had to abandon ship because I needed the domains working. They still send me a bill....as if I'm going to pay it....and my server access is still good but I don't have any domains there any longer. I suppose I could upload a bunch of crap to their server to try and slow it down or something... Anyhow, now I know they don't know what they're doing. They were called Authentic Hosting, beware!
