Direct TV billed me this month for an installation and receiver they claim they installed last year. What actually happened is I bought the Hughes HD receiver from Best Buy and installed it myself. They activated it after I installed it. This Hughes receiver appeared on my Direct TV account until they replaced it with a leased HR20-700 HD DVR. I was on the phone with them for three hours last night without success in convincing them I own the Hughes receiver in question. I said I wouldn't pay for the receiver unless they could produce proof that they delivered it. I ended up cancelling all Direct TV service and they turned off the feed last night. Anyone have suggestions on what I should do next? I've considered subscribing to Dish Network.
