Worst customer service experience

On December 31st a technician was ordered due to technical issues from the previous day. Anywho, the technician that came stated the issue is in the line and not the modem. Therefore, they will need to schedule for another technician to come out and fix the outside line. The appointment was scheduled for January 1, 2025. The technician called me an hour later to inform me that he does not work on January 1st and will reschedule the appointment for January 3, between 8am- 10am. I work from home and my family is depending on my income. I explained that to the customer service rep as well.

January 3rd around 11am or so, I get a call from customer service rep stating that the technician will be running late. He will be here around 12-3pm. Mind you I took the day off. I call customer service around 4 to find out the ETA. The rep stated that he did not see any notes as to why the technician is running late. Therefore my appointment still was scheduled. I waited and called for the 4th time around 6pm. The customer rep stated that the technician was on-site. 20 minutes passed and I waited in the hallway to see where the rep was. No one ever showed. 
I called the same rep again, only for her to tell me that the technician rescheduled my appointment all the way January 6th. 
Again, I work from home. It has been 4 days that I haven’t been able to work. Now Xfinity is telling me that the only appointment that they see is for January 6th? How can that be? 

I pray that I still have a job by the 6th. Meaning that I have to wait an additional 3 days.

I am currently waiting to speak to an agent. I have been waiting for 2 hours and 30 minutes. Unbelievable!

I would truly appreciate it if I can get the information to corporate.
