SiriusXM Turns bad customer service into Past Due bills I sold a vehicle and called to cancel XM radio but they didn't cancel but continued billing me.

My XM radio subscription was about to renew when I sold the vehicle.  Not wanting to incur another year's charge, I called and spoke with a customer service rep to cancel the service.  Of course he kept trying to upsell and sell service on the new vehicle, even after I provided all the information to cancel service.  After 10-15 minutes of listening to his pitches, I asked him to simply cancel the old service and I hung up. 

Of course the "customer service" rep didn't cancel the service, or it wouldn't be a Rip Off.  So they billed me for another year and I didn't pay since the car was sold.  After a couple months, I guess they realized I wasn't going to pay so they sent a bill for the first 6 weeks and want me to pay that "PAST DUE" amount.  If their customer service was worth a nickel, this would be a happy ending.  Instead it's a bully company that takes your credit card number and refuses to stop charging you even after you've canceled service.
