New Customer Having Serious Regrets

I just signed up for Xfinity four days ago and I'm already seriously regretting my decision. I have been calling customer service since last night, within hours of operation, but have yet been able to speak to a human. I started calling again this morning, again within hours of operation, and cannot get a human. The virtual assistant has not been helpful and my issue could have been resolved had I been able to speak to a customer service rep. I initially called last night because the info for my property details, for my cable installation, are incorrect; I have no idea who entered the information, but it wasn't me. In addition, the visit was supposed scheduled for the next day (today Monday 2/3). The tech who activated internet said I would receive a text notification regarding the cable installation; that did not happen. I went from the virtual assistant to a live chat agent to an advanced tech support agent. The tech support agent only corrected one piece of incorrect information but I was able to explain that, although not required, I want to be there when the cable tech comes to my home. My appointment was rescheduled for this Friday 2/7. This morning (Monday 2/3) at 5am, I received a phone call and text indicating the tech would arrive at 8am. I called the number back and spoke to a woman who said it was her husband who called. I could hear her husband, in the background, explaining, in Spanish, while his wife translated/explained to me in English. When I told her that my appointment had been rescheduled last night, she said her husband needed to call his boss. I asked for a call back, once he spoke with his boss, to ensure we are all on the same page and no one would come until this Friday. I never received a call back and now the tech/his wife aren't answering my calls.
