Scam 1: When you cancel they will tell you that you owe money for early cancellation, betting that you won't have or look at old contract date. Won't back down until you fax contract to them!
Scam 2: When they figure they owe you a refund, they will send you statements with amount they owe you.
They do not send a check. When you call, they will apologize and say it is on its way.
After a year, they void the refund and keep the money. I have called several times to talk to a supervisor and the phone connection strangely goes dead when the supervisor gets on.
