Registering address

So recently built a home and trying to get xfinity service however address says can not be found. And every neighbor on both sides of the street have xfinity. But cannot seem to figure out how to get my address to show up. When I speak to someone they have only said there is no service for that area. However it’s covered on xfinity coverage map and as I said every neighbor around us has xfinity already. Any help would be greatly appreciated.
