No service, no help

We recently moved into a new home and arranged to have the internet switched over on the day of the move. It did not work. We called customer service, who could not fix the issue over the phone and scheduled a Tech to come to our house in 5 days. We explained that we work from home and need the internet, so we were told we were put in some sort of waitlist to see if we can get an earlier appointment. Then we waited, no waitlist opening happened. Then the day of our scheduled appointment arrived and the Tech was a no show. When we called back to customer service we were told the appointment was cancelled, no explanation as to why, and we would have to wait another 5 days for a Tech to able to come out. When we asked to speak to a supervisor or manager because we cannot wait another 5 days, we were told the supervisor can't help and refused to let us escalate the issue. The only remedy we have been offered is a credit for the time we have been out of service and a "great deal" on a Peacock subscription.
