I was having an issue with my Directv recorder not being able to play the recorded shows. After getting the run around and getting it scheduled properly they offered it to me for free. I didn't even ask for it (I would have made the call in late August though). It was their way of apologizing for not getting the DVR thingy fixed sooner, I so LOVE Directtv. I have friends who have Comcast and have heard some HORROR stories about their customer service.
FYI I have been a customer non-stop for 17+ years.
