The best thing since sliced bread!
I called them last week to ask about the whole-home service. Before we could even discuss it, we discovered we had been paying for a 3rd receiver since we upgraded almost 4 years ago. We only have 2 TVs!! Apparently the install guy never returned the card or whatever it is he's supposed to return, so instead of replacing a receiver they thought we added one. And on my bill, I thought we had to pay for both of our receivers. The rep was quick to apply a refund, though.
I never did get a truly straight answer on the Whole Home Service, though. I called several times, and each time was told something different. Plus one of the reps we spoke to sounded very bored, and when I asked what was included in the Whole Home upgrade fee, her response was, "Yeah, they don't really tell us that information." It just didn't fill me with a lot of confidence.
In the end we decided to switch to U-Verse. We really needed to upgrade our internet and phone service, and they were offering a pretty sweet in-store incentive on the TV package which we can cancel after a year, so we're going to give it a try. Our neighbors have it and LOVE it, so let's hope our experience is as positive.
Had it not been for the great incentive, I think we would have stayed with DirecTV, although I have to admit their customer service has really gone downhill over the last couple of years.
