Annoying webhost

A host that i use really are getting on my nerves I have another blog where i discuss design and other stuff! But the webhosting account has been suspended for no reasons and the website has been replaced by a advertisement back to the webhost and a brief message saying account suspended. Its stupid how dare they! They dont own my domain so why are they allowed to now use it to advertise. They haven't even told me via email that they have done this.. it was only trying to go on my website that i found this had happened! Stupid cheap scammer hosts! I say you should all be cautious with what webhsoting you get as there really are a lot of scammers out there!
