Lack of followup by Comcast agents

Lack of follow up by Comcast. I have been on the phone for going on 12 hours this week. I've spoken with agents in Janaica, Mississippi, Phillipines and who knows where else. I have three accounts. I set up an account for my third house in July. I received an email stating a tech would be out to hook me up. None ever showed. I am remodeling that house so I wasn't too concerned since I have two other accounts. Then I got an email claiming I had an overdue bill last week for that account. I began calling and calling and calling to resolve the problem.Comcast has 1. the worst telephone system I have ever used, and 2. the dumbest customer service people I've ever dealt with. In any case, after many hours on the phone a tech came out, ran a line from the box to my house and we finally got Internet. I next spoke with a recording about the tech visit the next morning and then a customer service agent and billing person Friday night. I was assured that my bill was reset to when I actually recived service, that the change would be reflected in my October bill. Today Comcast, who strives to keep us connected, turned off my Internet. I didn't realize it until my GF had trouble using the Internet. I then got a Comcast call, picked up the phone and there was no one on the line. I called the number back and got a moron in billing. I explained the story. He couldn't help me. I waited some time with that irritating recording running, then got a combative girl in Mississippi who claimed to write a ticket for a supervisor to call me. I demanded to speak to a supervisor now. No way. Lots of excuses about COVID and on and on. Then she sent me to some department. A guy picked up and said hello, who am I speaking with and he promtly hung up on me at 9pm. Now I cannot speak to anyone. This is what happens when a monopoly developes. forum guidelines> Oh, the girl from Missisippi stated that my Internet would not be turned on until after the supervisor called which could take three days.  This is the service you get from government not a company. Comcast/Xfinity is the ONLY company in Collier county not staffing its stores. Anyone out there have any suggestion? I mean, Jeez, I have three accounts with them. You would think I'd get some service!
