I don’t deal with that stuff at all but I do know that through TW they have tv/phone/internet @ 99.99/mo for 12mo. promo going on. (TW has no contract compared to having a contract + isn’t there like a $300 install fee for FiOS?)
Other than that, I have no idea what rates you would be stuck with if you drop Internet through TW. If you call in they can answer all that through the billing department, which I am not.
Jeff pm the # it’s under and I can look it up for you.
