Rip off. Have automatic billing thru XM. Since they merged, they now are charging a $3.60 music royalty fee. Bill for the month just popped up. Could not find my info and wanted to argue that they did not have my visa for auto payment (although they have been charging to it for 8 years). Added 2nd unit-took 3 phone calls to get it activated. Sounds same as the airline rip off fees. Good thing they are not a restraunt. they would be charging for glass usage, plate usage, fork usage, etc.
