I am going through my AMEX bill and notice TWO charges by Serius XM. I have put my car on their service for $24.50/6 months. The two additional charges I get are for $129 and $49. I called AMEX and stopped the charges. I later contact serius and after transfer to transfer to transfer finally got their accounting department who agreed to credit the money back, although AMEX also helped quite a bit. Too bad, I was going to get the service on all my 4 cars, but after this, I put a stop on any charges from Serius XM on my AMEX.
Becarefull of the bogus charges.
