New SERVICEABLE home - Deemed Unserviceable WHY?????????

We have a new home that we are about to move into.  Prior to moving in we created an account and scheduled a technician to come out so that our services would be set up prior to moving in. Our address at that time was marked as serviceable. The technician came out and said we needed a coax cable pulled. Apparently the nearest pedestal is over 500 feet from my home.  BIG DEAL - cable can be run more than 500 feet.  Costs about .50/ foot.  Instead of any follow up, our account was then closed. We have been on the phone with representatives countless times and were told to go to a local Xfinity store.  Each time someone tells us they have "made a note in our file" and to give it 3-5 business days (this has happened at least 5 times at this point).  It has been weeks of the back and forth with different representatives. Each time we go back someone tells us there is no note in our file. When we describe our situation, we are consistently met with "your address is marked as unserviceable in our system, sorry." When we ask how they can make it serviceable again they tell us that a tech will have to come out, but they cannot schedule a tech because our address is marked as unserviceable. I am not interested in being contacted unless whoever can contact us has the ability and authority to fix this situation.​  I work from home so I need internet ASAP.
