XM SIRIUS Lousy Service Costs them a customer

I recently experienced such poor service from XM SIRIUS, I had no option but to cancel my service. Sadly, no one there gave a crap. A manager was supposedly was calling me back within 48 hours and that hasn't happened in 14 days.
The worst thing about this, for the cash strapped and customer losing XM, is that they owe me a refund, money they already had in the bank.

Why would a company not listen to a customer who has already paid for the company's services.


Go figure
