Auto pay with DN is a BIG gamble in my opinion. You think you see a strange increased bill due to simple programming changes, you should see some of the outrageous charges on my account due to past equipment modifications, namely when HD was first introduced and DN was offering free OTA antennas.
I saw bills over $500 more than normal for so called 'free' upgrades. It has been my experience these last 12 years with DN that it takes, on average, three months for them to straighten out mistakes on my bill, and perhaps as many as half a dozen phone calls.
You've heard the old saying, 'just smart enough to be dangerous'? That's DN CSR's, they all sound like they know what they are doing, but it is a rare DN CSR indeed that can actually handle/correct errors properly. I would bet that almost half the CSR's you get on the phone make things worse, not better.
My last run in with DN CSR was over DirecTV making me a great offer for an entire year that would have saved me most of $500 for switching. I contacted DN and was offered a $40/month credit for 6 months and a $10/month credit for 12 months and free showtime/hbo. Of course, my bill showed no credit and full charge for showtime/hbo. When I called them, the CSR said that they could see an attempt to credit my account, but it didn't 'stick'. He said he would straighten it out. That was over 2 weeks ago and my online bill shows no recent activity.
I will have to call in again, at least once more, probably twice before getting it straightened out. The absolute only saving grace is the fact that cable and DTV CSR's are probably just as bad.
Luck all,
George
