Been a DirecTV subscriber since the Bronze Age. Sunday Ticket (with its access to Bills' games) was the draw. But the past few years, I find that I've been recording the games while getting on with my life on Sunday afternoons. I check the final score. Bills win and I'll watch. Bills lose and I hit delete.
I don't have any real issues with customer service, but if the Sunday Ticket package becomes available on another platform, I'm done with DTV.
Their pricing is getting ridiculous, but my wife's employer partially subsidizes the cost (as well as the cost of our internet connection, Netflix and other streaming services, and her cell phone), so I can't grouse too much. But like I said, if Sunday Ticket goes, so do I.
