Sirius XM Radio Bad service, stealing and lack of good management New York City NY

I purchased a new vehicle almost a year ago and called Sirius XM to start my new service and cancel my old service on the vehicle traded in. I was told that the cancellation on my old car would credit to my new account (a years worth of service almost) when my free trial ran out.  The person that setup my new account did not cancel the other service and left it on. Sirius is refusing to add the 10 months of service that ran out on the old vehicle to my new one.  So their employee dropped the ball canceling and transfer the service and then George ID # 5468 refused to fix the error caused by one of his employees and told me he was the only manger that I could talk to and that he couldn't manually input a credit.  I have three different radio subscriptions with Sirius and they would rather let me cancel all of them according to George than fix the error.  I feel like they just stole $160 from me. They are losing a longtime loyal and multi radio customer. Also I was told by the rep tonight that who ever has my old card could have called in and renewed again on my credit card because Sirius left it attached to the old acount. Do not give your credit card information to this company it may not be safe and the practices are very questionable.
