Problems with XM Service

[Bluto]

I usually don't like to slam a company but I feel the need to rant a little. I had XM radios for a couple of years and never had a problem. But when I wanted to discontinue their service, that's when the problems started.
In an effort to cut my spending I chose to cancel and called on 2-11-09.
At that time I had already paid for service in advance and had a credit due me of $256. They discontinued my service right away and said that in 2 to3 weeks the credit would reach my credit card. It's now 4-9-09. Still no credit and after many many calls they tell me that a supervisor will call me and I still have not heard from one.
Their customer service is just a phone bank in India. Their people are stupid and won't address the problem nor will they return my money.
The sales office calls me from time to time and asks if I want to sign up again. I tell them the story and still get no response or money. They just say, "I'll write a note and someone will call".
So just beware of this company before you too have a problem. They like to take your money but have a rough time giving it back.
