We just dropped them after four years. Having been (deservedly) suspicious of their business practices, I never gave them any access to any sort of auto-pay.
I had to have discussions (!) with their pushy phone answerers every year... I would insist that they give me a price break due to terrible sat. reception here at about Lat 47, and finally they would give me a one year contract for about $90 to 100. Most of their phone people did not understand even the basics of satellite reception - one even told me it should be perfect for me since it came from the Sky!
In the last year their "promo" spots, i.e. commercials, have gotten so darned numerous that it just got too irritating trying to find some music to listen to. We only ever used them for about 6 music channels anyway. It reached the point where I could switch channels 4 or 5 times, and run into another of one their commercials on every channel at once!
Last year, after getting the one-year "deal" again, and having to listen to the operator lie to me that they never gave an annual contract to Anyone, and then finally doing just that, again, I decided that if things did not improve, I was leaving. We have two vehicles and that was running us about $200./year for both. Heck, for that kind of money I can buy a late model iPod for each vehicle!
BTW, the operator this time did not try to false bill us or "slam" our account as they have dome a couple times in the past. Well, not yet anyway. That monster multi-million $$ fine by the Feds a while back must have got their attention. That, and the registered letter I sent in to confirm my cancellation. (My back up plan would be filing a complaint with our state's AG office.)
Years ago, they offered a reasonable music service, but it's gone downhill a lot.
Funny thing, after all that has transpired, last week we get a snail mail offer for $30. for six months. It went straight into the shredder.
Apropos of whatever our quoted "full price" was always $15./month per vehicle. I have never paid that... but they sure wanted it. Now I wonder if they quote different rates in different states? Weird.
