Horrible service and supervisor hung up on me.

I had an appointment for 3-5pm today.  By 5pm no service tech had shown up at my home. I chatted and was told there would be a tech here 5-8pm. At 8 when no tech had come I called and talked to a customer representative.  He said the next available appointment was 4 days from today.  It didn’t matter that I had an appointment but no tech had shown up.  I was not a priority for tomorrow. The appointment for the next 4 days were full.  I have had no internet or cable for a day and a half already.  My no show appointment is just too bad and I go back to the bottoms of the list for the next available time.    I spoke with a “supervisor” and she told me how sorry she was that no tech showed up but there was nothing she could do.  I’d have to wait until the next available appointment in 4 days.  As I was arguing with her I asked to speak with her supervisor and she assured me they would tell me the same. I insisted to be transferred and she said of course and hung up on me. This is the most unprofessional experience I have ever had the displeasure to experience.  We will be canceling our Xfinity’s service.
