good luck with that. I've got a similar situation and they absolutely bend you over when just wanting internet. I've got their highest internet speed and I pay $125/month with phone service(actually more expensive without one bundle) Just ridiculous.
Ive been with dtv since 1997, back in the good old days when you could test and emulate and get free premium channels. I just dumped Windstream and went to twc for phone/internet last week. So far, so good.
TWC ($50) for internet + DTV ($100) is what I have, works great, plus my wife streams Amazon Prime, and Apple TV all the time, never seems to have a problem with the internet speed
