You don't even have to send the CC company a letter... Call them, and ask to talk to a chargeback manager... They'll send you a packet that explains exactly how to do it and take all your information down in order to start the process...

Just make sure you have your ducks in a row before you start... If the hosting company has anything that contests what you say, the CC company will get real pissed off...
