Xfinity does not show confirmed technician appointment

I moved into my new apartment 06/30 and needed to transfer service. I called and the first agent was horrible, unpleasant, and unprofessional. The apartment complex has a contract with Xfinity and she didn’t even know how or that even existed. She took about an hour and put me on hold several times. She finally did, and once I moved I unfortunately see that there is no coaxial outlet.

I have a TV box and work in healthcare from home. The second agent was much more pleasant, and advised to schedule a technician to stop by and install one so the service would be much faster. I work with patients, and have a patient portal system as well as other applications all at once so I kinda needed the faster service. He set up an appointment to come on Sunday 07/09/2023, between 4pm-6pm (earliest Xfinity could provide), and I received the confirmation appointment the same day. He recommended to keep calling and see if there has been any cancellations.

So I did today. The rep I spoke with said the earliest he could provide me was MONDAY! HOW? If my appointment was the day before! And asked if he even sees an appointment and he said no! This apartment complex has a contract with Xfinity and it shouldn’t have taken that first rep near an hour to transfer it over the first time! I asked for a supervisor SEVERAL times and never spoke to one. This is highly upsetting. I need somebody as soon as possible.
