I was charged $100 for an in-home technician visit that I was not informed of in advance.

I understand that I was charged because the problem was within my home and not with Xfinity; I am not claiming that the problem was with Xfinity. I am saying that I was not informed beforehand that I might be charged a fee, and I never would have scheduled the technician visit if I had known. When I scheduled the appointment through the chat, I was not informed. I was also called by Xfinity the next day to confirm whether I wanted the appointment, and I wasn't informed of the fee during that call. I also received an automated call the day before to confirm my appointment, and I was not informed of the fee during that call either. At no point was I informed until the charge was posted on my account. This is absolutely unacceptable.
