Few months ago, I’ve decided to try out a Xen virtual server service in a German provider, xencon. Then I decided I had a better solution (also Xen-based), and I don’t need xencon any more. However, it turns out that it’s not so easy to cancel the service. I had similar problems with two telecom providers in Poland. I said I want to cancel the service and they kept on billing me.
Dreamhost however, is awesome: if you want to, or need to, you can actually close your Dreamhost account on-line! They kindly ask you “Please, stay!”, but you have a button to press, stating that you really want to close your account.
This is by itself an excellent reason to open an account there.
