SiriusXM Sirius Satellite Radio Sirius' treatment of customers is utterly APPALLING, Internet

I have NEVER in my life been treated in the way this company has treated me. 
This people are horrible. I don't understand why anyone would EVER get this service. 
With such horrific costumer service, I don't understand how this company is still in operation. 
By giving this review, if I can save just person from the trouble I've been through, I will feel better. DO NOT GET SIRIUS!!
I have been given the run around over what should have been simple fixes for them. 

Long story short--well after my initial 3 yr subscription ran out, they charged my now EX-husband's credit card for a 3 yr renewal and refused to refund it on his card--over $500! This was done with no phone, email, or mail notification. 
Since Sirius on my car had stopped working almost 2 years ago, I of course would have never noticed. " You should have called us." Oh really? Now why didn't I think of that? I DID call several times, you idiots. And you couldn't fix it. I gave up and let it go. My mistake- I should have called and demanded a refund for the remainder. 
How was I to know over a year later, you were going to take it upon yourselves to put an unauthorized charge on someone's credit card that I hadn't even talked to in a year? 

That would be bad enough, but when I call to get the problem fixed, I was given a complete hassle. Had to spend over 30 minutes on the phone with these people on Christmas Eve! I was FINALLY told I would get a refund check in 7-10 days. I've waited. Called today and guess what. They haven't sent it yet!!!!! So now they tell me it will be another 2 weeks. Were they never going to send it? What are my options if they don't?? Do I have to talk to an attorney?
Meanwhile, it has taken so long, I have to go ahead and send my ex a check without getting the refund first. I live pay check to pay check--especially at Christmas. This has put me in a very bad situation. 
Do these people care? NO. This is unbelievable.
