For the past 6 months, neither myself nor anyone at SiriusXM can access my account (it gives an error message on their end when they try). I'm now on my 3rd trouble ticket since September 2011 with no resolution in sight, i can't even cancel my account since they can't access it, nor can they tell me why I keep getting billed and what the charges are for.

Any ideas? I'm at a loss here, other than calling my CC to dispute since Sirius can't tell me why they are billing me.
