Support and communication- Xfinity Customer Commitment

I signed up for Xfinity internet and opted to add Now Tv streaming service. Now Tv would not stream to my Roku device (as advertised). I reached out to Xfinity on multiple occasions to troubleshoot. The attempts to access service were unsuccessful so I cancelled the subscription and switched to cable. Fast forward to this month's bill. I am being charged for Now TV. Every time I have tried to reach out to Xfinity regarding the charge, the chat magically disconnects and is unavailable. This is usually after I refuse to sign up for Xfinity mobile. I am beyond frustrated. 

I also have been waiting for over 30 days to have my line buried in my yard. On multiple occasions I have been told that a service appointment has been scheduled to bury my line and would need to be there between 8 and 8 pm. I have not moved into my new home so it is an extra drive out to the new house and a day of waiting (had to take off work). Monday, I was supposed to have an appointment. I still had not heard anything Monday afternoon. I called Xfinity and was told there was no appointment scheduled. I was frustrated but I rescheduled for today (Thursday) and made sure to confirm yesterday that I had an appointment scheduled. Yet again, there was no communication and I reached out to Xfinity via chat/text this afternoon. They told me there was no appointment scheduled. Another day wasted. After messaging with an agent via text, the agent has continued to harass me about signing up for Xfinity mobile. I also have had several calls from Xfinity recently trying to sell me services for Xfinity mobile. I have gotten the calls while at work and when I try to make it clear that I will not be switching to Xfinity mobile, they continue to ask me about my current mobile provider and give me more information about the services that Xfinity offers. I am not interested and frustrated that I have been continually harassed. 

Xfinity is the most reliable internet provider in my area but I am getting very frustrated with customer service and the harassment about switching to Xfinity mobile. The chat function is only intermittently available and wait times are long when I have tried to call. I am interested in hearing more about the "Xfinity Customer Commitment," because I am definitely am not happy with service this far. There is a lack of communication, charges for services that were not available for me to use and continual harassment about new services.
