are you serious? not offering a refund when you fail to deliver the product is something that makes americans absolutely furious. it's one of the only sacred consumer protection issues here.

Right now apparently they're treating us a lot better than the European isps. Outside the HN bubble no one is really surprised to hear about a service quality problem in Europe though.
