Continued internet issues

I have been having continued issues with being dropped and being kicked off VPN. I have had to call multiple times and each time I call the wait time is 15-30 mins.  Finally get in touch last week and they try to schedule an appointment 5 days from my call knowing we work from home.  This is not acceptable.  Tech arrives and identified a tap and amplifier issue but says he cannot fix that is another dept.  Really?  He said he will put in a ticket.  Did not hear from Xfinity and had to call again and waited on hold again. Rep said there was no ticket. Again unacceptable.  She spoke with the engineering dept and they claimed there was no issue. I told her yes there is and I I want someone to come fix the issue. She said they would send a new tech and be in touch with appointment time. Again no phone call and had to call back yesterday. Again Rep tried to schedule someone 5 days out  again unacceptable. She got me on the schedule for this morning between 8-10. My work VPN still dropping and continued internet issues.   Now I receive a call that tech will be arriving outside scheduled time but does not give me time. Xfinity OBVIOUSLY does not care about their customers.  How hard is it to understand urgency in some instances?  How hard is it to provide proper service?
