No service after almost 2 months

Just wanted to make people aware about how unorganized and unprofessional Xfinity has become.  I have a new construction residence that I recently moved into.  The address is brand new and needed to be added to USPS.  I knew I was going to need to get ahead of things to be service to my residence in a decent time so in May I began making phone calls.  Here is a timeline of events:

Middle of May -  Called and spoke to a representative who stated that the address was not found in the system however call back at a later time.  Informed me that my address may be just out of the 300 feet range from the closest person with service however they will look into it.

Beginning of June -  Called back asking the status.  Was informed by a representative that my address is now eligible for service and are willing to set up a time to have comcast installed.   Set up an account, put a deposit down on the service and even talked about switching to Xfinity mobile.  Also set up the date a couple days after we move in.

Beginning of June - Call again to confirm that a tech would be coming out to install our service on the date agreed upon.  They explained yes however a survey needed to be done.

June 17th - First tech arrives.  Explains that Xfinity construction has not ran a line yet.  Steps away and calls a supervisor.  This supervisor explains that they are willing to construct to my residence in order to feed other homes on the roadway.  The distance is approximately 690 feet.  Explains that I will receive follow up from someone and that they were going to actively look to pull permits.

June 27th - Received an email from the construction team quoting approximately $15,000 out of pocket expenses to run a line to feed my service and then in turn feed other users!  This email is a result of my follow up call prior to my first service tech coming.  Not the because of the service tech calling the supervisor who verbally approved of the construction.

June 30th - Called customer service again and explained the aforementioned timeline.  They ensured that another senior technician was going to come out and run a line to provide service.  I asked numerous times are you sure and they replied yes I would definitely have service with this new technician.  Scheduled a date of July 3rd for the tech to come.

July 3rd - Tech responds to the residence to explain the exact same thing to my family as the first tech.  Tech leaves his phone number and says that he will follow up with me by the following tuesday (3 business days).  I waited for a follow up until  the 14th and nothing.

Each representative I spoke with ensured us we would have service provided to us at our residence.  Each tech came out, and in person explained that they would provide good customer service and keep us in the loop.  Both provided phone numbers and names.  Neither one followed up with us and ignored messages and phone calls.  Also, the deposit I put down for service was turned into an Xfinity credit, not even a refund.  That's how customers of 20 years get treated.

This is a complete disaster and the fact that Xfinity wants me to pay that astronomical price to have another 300 ft of line ran is absurd.  Knowing that once I get service, several neighbors will start feeding into out line and get service for free.  I would like a follow up from someone from supervision in reference to this complaint.
