On one hand I am a former employee and a almost 20 year customer. They also used to be my "go to" when clients asked me what tv service they should go with. They were always the most reliable and had the best UI (and discretes). But since AT&T they have moved from as I put it "they all suck but Directv sucks the least" to "as crappy as everybody else".
As for broadband data caps, I have had a 1TB cap on my service for about 5-6 years now. Have never come close to hitting it. This month I started getting warnings that I was close to my limit. Not really sure what changed, my household admittedly uses a fair amount of data but usually in the 500-750gb/mo range.
Interesting that others are suddenly seeing the same thing. I wonder what the deal is.
I am a trained professional..... Do not attempt this stunt at home.
