CONSTRUCTION TEAM/SERVICEABILITY

I have had a ticket started to have the service line extended to my new property.  Things were going smoothly until I received my estimate of almost $6,000 and asked for a cost breakdown.  Fast forward over 2 weeks later, I'm still waiting for the construction team to contact me.  I have volunteered to do the trench work myself to lower the cost.  I am actively checking in with the chat service so that I CAN GIVE XFINITY MONEY.  Why is this such a redundant process???  What company in the 21st century doesn't have a direct line to call and speak with someone about construction issues?  I have been getting the runaround for weeks on this and I would like something to be done to resolve this in a timely manner.  I am under a deadline with my house closing in less than a month and I NEED INTERNET SERVICE TO WORK FROM HOME.  I am almost to the point of filing a complaint with the FCC.
