XM Radio is a pain

[HummerJim]

I did not renew my XM after the free trial period on the H2 and specifically told them once in writing and three times on the phone that I didn't want it. They still send me billing for it even though I never use it and cancelled it, about every 3 months. Is this just me or is it that hard to stop from getting mail and notices of overdue billing on something I cancelled and don't use? I'm about ready to go to the BBB and report them. I got a bill in the mail today and I got on the phone with them today for 40 minutes and they said they have no record of it being cancelled - this has been going on for a year!
