Xfinity lying and changing my service against my express permission

I've been going around and around with CS reps for several weeks. Fighting absurd add on fees and keep getting lied to by all the Indians that don't know how any of their systems work. First they were purposely throttling me for using bridge mode on their gateways which is a welp known fact on the internet at this point. They do it to try and convince people to use their shady gateways which spy on everything in your home and literally sell part of your bandwidth to random other people. It's illegal in itself but they keep doing it. They eventually sent me a new modem claiming the old one was defective. It was not. It just won't work properly in bridge mode which I require for work. As soon as you enable it they throttle you 90% and act like your equipment is bad to trick you into using theirs. The new version modem they sent did the exact same thing as I expected so I just started using my equipment with it in normal mode and Wi-Fi's turned off which creates an unnecessary subnet. They told me it would all be free but immediately tried charging me for the modem and shipping. After 3 or 4 reps telling me it will be corrected and tyen doing nothing I locked my debit card and played chicken with them. Fix the fees or you get $0 and I go to Tmobile. Eventually someone corrected it but not the whole thing and the bill was still off by a few dollars. I did not let up and made them fix the rest of it. This tooks several weeks. Then they said my bills would go back to normal afterwards but guess what, yhe next month there were more additional fees added on. I got on chat with support again and they said it was because I didn't return a modem. I said nope, you told me I didn't have to because it was broken and provided no means of returning it. They said okay we'll remove the charges and would gige me $5 credit for the [Edited: "Language"] around yet only gave like $3.50. Whatever. Every time they say they'll correct the bill though, it's always a few dollars in their favor vs what they agreed to. They just keeo trying to squeeze any bit of extra money out of me they can and I refuse to allow it. Then this last time they tried up selling me to a higher plan (for the 3rd time) and I specifically said NO. An hour after I finished the chat they went and upgraded me anyways. Now I'm totally enraged at this point and went back to tell them to put it back to what it was because they did it without my permission and they said they had to "escalate" it like they always do when they want to ignore you. It's been two days and nothing has changed. My card is locked again and they will get absolutely nothing until they put it back. If they do not, I am switching providers and filing a police report for all of the blatant criminal activity going on with xfinity. I have ALL of the chat records saved on my phone.

This is a last ditch effort to hopefully get the attention of someone at the company that's not a shady out of country contractor that can sort this garbage out [Edited: "Inflammatory"].
