This is a joke nor is it legal. I need this resolved now

I have been a customer with xfinity for a few years now. I signed up for a locked in rate of $80 per month as I needed to be able to work from home, and my kids be able to play their games and stream TV. Initially there was no issue. The bill stayed the same for a while. 

Spring of 2023 i noticed my bill slowly increasing in cost. By $5..then $10.. and so on. No reason behind it. It continued for a while, and now it's at $50 more than my "locked in" price. I tried tried talk to customer service and the disregarded or disconnected. I noticed they were charging me for a second router and a second streaming box when I only have one.. which was included in the package for no extra cost on my bill. Customer service wouldn't listen. Then the real issue started. 

October 2023 is when I contacted them about the additional charges. November 2023 I paid my bill at the beginning of the month as I normally had. November 20 I got a notice shut off for missed payment. November 25 I paid my bill A SECOND TIME. December 7 my service was shut off for "non payment" at this point I did not have the ability to pay until my paycheck came in as I had just completed holiday shopping and paying the second time in November. I contacted and informed them of this and set up for a payment to come out. Internet was restored. December 18 I was charged. Then on December 24 I was charged 67.40. December 25 I was charged another 67.40. I requested a refund because why was I charged multiple times. December 27 they refunded me. January 4 they shut my internet off and claimed I canceled my payments. I paid AGAIN.. and then received my regular bill for January.. which I again paid. (Keep in mind all these bills are roughly $120-$160). January 25 I received ANOTHER shut off.. so I paid AGAIN but customer service was "so kind" and charged me 3 reactivation fees. I SET UP AUTO PAY TO AVOID THIS ISSUE! February 10 I paid again. Received another shut off notice on Feb 18. Paid again Feb 20. In March 3 i paid the bill. I was shut off again on the 5th. Issues ANOTHER reactivation fee. Then was charged AGAIN on March 16 and again MARCH 25. I turned auto pay off. April 5 i paid the bill. April 10 my service was terminated for non payment. I paid more money I didn't have. April 25 it happened again. I paid even more money. May 7 i paid. May 20 I got a warning of disconnect. May 25 I paid again. June I paid on the 4th, 10, and the 25. I now received yet another shut off notice. I can't do the robot chat thing because it is useless and unhelpful. Customer service isn't helping either. I have asked to escalate this many times and the hang up or threaten to shut my service off and black list me. I have paid 21 times. TWENTY ONE TIMES IN 9 MONTHS AND YOU MEAN TO TELL ME MY BILL IS NOW $466?! THERE IS NO WAY!!! I WANT TO SPEAK TO SOMEONE HIGHER UP ABOUT THIS the refusal of the outsourced employees to escalate or help the customers who have stayed through all the bs is astounding and I have a strong inclination to cancel and leave. How you gonna fix this xfinity?! Because I'm pretty sick of it!
