Complaint Review: XM Sirius

Like many, many other XM Sirius radio listeners, this service is getting worse. I live in Kansas City and over the last 4-6 months the signal drops out completely, or will sound like an alien that you can't understand. I have a factory installed radio that worked falsely until 4-6 months ago. It can be clear skies and no obstacles, and the signal will just drop out. I replaced the factory antenna at my cost, but made no difference. It is extremely frustrating as you can't even listen to a complete song, or news cast. I have heard there is some kind of interference with T-mobile cell sites, that has been addressed, however T-mobile  says it is XM Sirius fault, and XM Sirius claims it is T-mobile's fault. As you can imagine this is going no where fast. I have had my service for over 10 years but will not renew my service when due. When I have contacted customer service (more like customer no-service) they are unconcerned, and only interested in upgrading your service. Each time you call you will contact an off shore call center (India), then you have to demand to speak to customer service agent in the US. As a matter of fact I am thinking of filing a class action lawsuit, as the company is charging and promoting a service which they can't deliver. I would be interested in hearing from other customers about joining a class action.
