No help on downgrading service and agent muting and sitting on the phone as I am typing this complaint and I have been given the run around

I have spoken with 4 representatives. my complaint is with the first, third, and court representative which provided nothing but condescending responses and refusal of escalating my call to a manager. I have been on the phone for 2 hours and 20 mins trying to resolve a simple downgrade in service. the first employee stated she wouldn't be able to transfer me unless I give her a date on payment of Internet service. she proceeded to say their was IT issues and then disconnected the call. once I called back and got transferred to the retention line David negligently kept me on the phone for over 1 hour and refused to escalate my call. he stated his manager wouldn't be able to help me and that the system automatically imputes a Comcast email which I do not have. then he proceeds to tell me that he will reverse everything and try again and I told him not to do so and to transfer me to his manager which he claimed approved my downgrade in service. he also stated there must be something wrong with my email. he also stated why did you call me as if I called him personally and not Xfinity. I informed him that I would be making a complaint to the FCC and then he stated he would transfer to a manager and david transferred to a agent in internet Elton. david was very unhelpful. in doing this as elton wasn't a manager. elton then stated he could only transfer me to the mobile department or his manager. elton then stated he would transfer to his manager and then the line was disconnected. I called back and an agent stated that I don’t return my equipment as I never rented equipment. Then later a internet personnel Shay was so helpful but couldn’t help in the way needed then she transferred me to an agent back in mobile to make updated changes and the agent is silently sitting on the phone as I type when I asked him to repeat or verify my email he stated he was talking with his supervisors to do so  after me requesting a super visor for 3 hours and 30 minutes. I am being treated unfairly and targeted once these contractors receive calls and read through the notes. I will hater will everyone on this board to file a class action suit against comcast poor management and relations.
