I'm having almost exactly the same issue with Comcast and have wasted so much time trying to get service. Please send an update or private message when or if you get any solid information on how to get in touch with the right people. Thanks!
Hi Cfan6 -- I can help with getting your tap constructed. Can you send me a PM with full name, address, and phone number please?
