I've had a few issues with billing myself having been a DirecTV customer for many years... however, all it's ever taken for me was a phone call and charges were dismissed. Maybe the time difference makes all the difference. Try calling around midnight and see if you get any better customer service.
Also, when I was having a difficult time with them not so long ago... I called and was quite adamant about getting someone out to the house to get their equipment off my roof and pack it all up. Eventually, they put me on the line with a senior manager... they certainly didn't want to lose me as a customer (all the money I've been sending them) and fixed all the billing issues, sent replacement boxes, and told me that my old boxes were obsolete and that I could just take them to the trash, as they had no use for them.
I was told, and it's been verified, that everything except the digital boxes themselves belongs to me.
So, if you can find a digital service that will talk to the dish you already have, that may be a direction to go.
