When I bought my new GM vehicle it came with XM Radio. After the initial trial package expired I did not renew the service. XM Radio is by no means commercial free radio. XM trying to regain my interest sent me a promotion offering three months of service at a cost of sixteen dollars and change. I called and accepted the offer authorizing the THREE MONTH offer at the sixteen dollar rate. I paid for the service via debit card. That was in April. I soon stopped listening to XM, I could'nt stand all the commercials, why pay to listen to them. I later sold my vehicle and while doing so pushed my on-star system to make notification. I told the on-star advisor to dicontinue all services affiliated with it which includes the on-star security, XM radio and the intergrated phone. Now in November I get a bill from XM radio saying I owe them $32.98 for service AFTER the three month promotion I agreed to. According to XM they will continue to bill you EVEN after a promotion, even if you did not authorize continued service. I have spoken with the XM billing department who say's they will send the bill to collections. They apparently like to get you wrapped up in a promotion then hit you with a bill demanding payment six months later. I don't mind paying for something that I authorized because I enjoyed the service, however, I was not impressed with the non-commercial free music and had no intention of extending the service promotion. Bottom line is XM radio sucks, and so do there representatives. They need to HEAR the music of customer dissatisfaction. If you really want commercial free music, I suggest burning your own favorites. XM radio does not make music for easy listening. By the way on-star did what they were asked. On-star in my opinion is a great service. Let everybody you know about XM radio underhanded business.
