Xfinity Comcast website AND app completely unusable.

After a crazy ordeal trying to even sign in on the app, then another ordeal trying to pay a bill which I should not have had to pay because I returned my equipment long before another fee was charged, I tried to sign up for internet again. But there is no way on the app or website for me to do that. There is also no way to contact a human. Guess I'm forced to go with CenturyLink.
