Their customer service has been good. They cant get the "On Demand" function to work correctly on the DVR. They have been out to service our DVR three times. We are on our third DVR and second modem. I am stuck with them for 11 more months before I can change to something else. I do not recommend them in Dallas. I had U-verse in Austin and they were OK except they would have a lot of outages .
It took several service calls and customer support calls to resolve the outages. Once that problem was resolved, service has been steady. Internet speeds (up and down) are reliable, and TV quality is very high.
