Wouldn't turn on (again), and found yet more billing trouble

Well, I got home tonight after being out to see a movie, and settled into the couch to watch some pre-recorded television. Once again, the receiver wouldn't turn on. I gave DirecTV a call immediately, and then proceeded with some troubleshooting on my own. Pushing the red reset button did appear to reset the receiver this time, but then a moment or two later, everything went dark. Eventually, pressing the power button on the remote turned the box on, and I waited the 5+ minutes for it to boot up. It appears to be back in working order now.

DirecTV couldn't explain the problem to me (no surprise there), but I took the opportunity of being on the phone with them to inquire about my billing question (the $55 charge for a non-returned receiver). The woman I spoke to said that the escalation to their billing department had been closed for no apparent reason. She's reopened it, so hopefully I'll get my $55 back someday... otherwise I guess DirecTV just wants to have a dinner or two on me.
