I am at a loss and have no idea how to get this company to help me get a new Line put in the ground

This company's construction department is a joke. This is not COVID related so that is an excuse if they use that as a reason no one has been able to help me for over 8 months!!!, No one has been able to get his right or provide when a construction ticket will be worked. I have been trying to install service at a new construction home for over 8 months now. I have gotten the address added to the database, then they scheduled an install and took installation money, then they say I need a construction request and many of the reps on the phone say they put in this request but month After month a Xfinity van shows up with a in home team technician ready to ask me ok I have The box to install it. Then looks at me confused and says where do we hook it up at? I say you tell me! They say there is no line here for us to hook up the new equipment I say I know. Then the same conversation happens ok, we will have someone come out to run a new line and tap into the house next to you! This never happens! We are so beyond frustrated!! I have been told multiple “New Construction Line installs” have been put in and I have yet to see anyone and no one ever comes other than your in home installers who can’t do anything without a physical line overhead or buried that comes to my new house! I have probably talked to 20 installers that show up here! This is so beyond ridiculous!
