Xfinity won’t fix broken line

I have had 10 plus calls, 6 technicians, and 4 requests for a line bury. I even had the north area manager for Sacramento number given to me and he no longer returns or answers my calls. Every time I call support I either get hung up on when they realize they cannot help or get a run around and have a tech come out to then see the issue. A line was cut before we bought this house last year. It’s under the road somewhere and they don’t want to address it. I have had soo many come out and they just give up. There is no communication and horrid direction. The only team that can request a line bury is dispatch and the customer support team cannot reach them. All the can do is keep requesting. They even missed a line bury date they set. It’s been a joke and to me they have no real care for getting this done. I have to settle with horridly slow alternatives and double up on them. I don’t live in the woods. I am in Citrus Heights and all my neighbors have internet. I mean maybe you are doing me a favor but in reality you missed deadlines you set and now your support team just flat out ignores calls.
