Complaint Review: SIRIUS Satellite Radio

We owned a vehicle for several years that had SIRIUS Satellite Radio.  We traded the vehicle in April 2009.  We were paid up until November, so I let the service continue because I listened on the internet. SIRIUS kept sending me invitations to renew for a super deal etc.  But I declined.  When I failed to be able to access the system, I assumed the service had ended and that was fine.  Then, much to my surprise, in February, I get an invoice for $36.90. When I call, they "explain" to me that they AUTOMATICALLY RENEWED my subscription as a "service" to me!!!!  What????  I questioned the supervisor, John M., about the legality of this and he indicated that the billing practice had been tested in court and it is legal.  I can't believe they can renew me without my consent!  Then when I went online to cancel it, I discovered that I could do everything else to the account but cancel it!  Surprise!  The ONLY way that can be done is by a phone call.  So, I called again. This time they informed me that the account had actually already been sent to a collection agency on Feb. 18th.  So, when I call the collection company, they say the account hasn't hit their books yet.  I casually ask the person from NCO Collecting Agency, "Do you get a lot of complaints about SIRIUS Radio?"  The lady laughs and says, "Oh, don't get me started!"  Obviously, they also know this is a MAJOR scam.  If this practice isn't illegal, it certainly should be; because it is clearly immoral!  It is companies like SIRIUS that give all business people a bad name!
