Installation delayed for 3+ days

I am unbelievably frustrated. We had our install/ transfer date as Saturday. The text showed up and said there are no fiber optic clients to our house because it's never had Xfinity before. He called and set up someone who was supposed to come and run the lines first thing Monday morning. This morning a text showed up to install again and said he couldn't because there aren't alliance. I called and said we can't get it installed. Then at 3:00 p.m. someone showed up and said they were here to dig the lines. He was able to complete it in about 45 minutes. I called customer support and asked if someone could come out today to install. I waited on hold for over an hour. Ended up speaking with a supervisor who said they were talking with the tech team who would get someone out here today or tomorrow early at the latest and someone from that team would call me back. It is now 10:00 Eastern standard Time and no one has called me. We've had Xfinity for over a year and really liked the service. That's why we wanted it at our new home. But no one is able to help us and assist us. I work from home. I need Wi-Fi to be able to do my job and now we haven't had it for 3 days. We also don't even know when a tech will come out to finish the installation. His entire situation is horrible and frustrating.
