I would call TWC and ask them about the data caps. They had them in the paperwork when I subbed to them back in '08, they just have never been enforced. The Cox here in PHX had a 400-500(not sure how much it is exactly), limit, but do not enforce it, unless you either exceed it greatly(TB of usuage, or every single month going over), so most people still think they do not have a limit. I only found out about it, when someone had mentioned it in my old office, and I called Cox and asked them directly about it. That's when it was disclosed to me. They still tryed to dance around it until I made them answer yes or no, then explain.
