My new contract was supposed to be $45 and it is $80. They lied and they won't fix it. $420 I'll be overcharged!

I'm a 20 year customer who has never paid a bill late.

My contract for internet 800 speed was $30 a month.  My discounts were expiring soon and my plan was more than tripling in cost.  I contacted chat on 1/27/25 for a new contract.  After 2 hours on chat they said they found another 2 year contact for $30 for the same as what I had and it was all set-up and approved my a supervisor and they gave me a ticket number and said they just needed verbal approval and someone would call me in 15 min.  No one called me so I called back to find out the ticket number they game me was fake, the plan didn't exist and they contact was imaginary.  So they I spent like 10 hours on chat and calls over the next month trying to get them to honor what they told me in writing.  They wouldn't.  Finally on 2/25/25 I got chat to send me a contact which they said was for $45 a month.  I questioned them extensively about all the details and confirmed the discounts and ongoing monthly cost of $45 repeatedly.  They emailed me the contact and it said at the top "Due Monthly $45", but in the details I couldn't see enough discounts to get the listed plan down to $45 month.  I explained all this to the chat rep and said to me it looked like it was going to be $70 a month and I couldn't see the extra $25 in discounts.  He assured me repeatedly in writing that it was for sure $45 a month for 12 months and that he could see the rest of the discounts on his end.  I told him I'd already been lied to and was very concerned I would approve thinking the $45 that he was telling me and that it said at the top and it would actually be $70.  He promised me that wouldn't happen.  I got my first bill and it was all lies.  It wasn't $45 or even $70, but $80 a month.  So I'm being charged $35 a month / $420 over the 12 month contract that I did not agree to.  Just got off an hour and a half call and they won't do anything about it.  Even though it is writing.  Even though I clearly said in writing I was only agreeing to $45 a month and not $70 and the rep assured me it was so.  Everyone I have talked to has lied and they won't do ANYTHING for a 20 year customer who has it all in writing.  Nothing at all!  Not even so much as a courtesy credit.  They can just lied and trick and they won't do anything about it.  Don't believe anything they tell you on the phone or on chat.  They will all tell you the last guy lied and they aren't liars and yet then you find out they were lying to.  No one will help you or make it right.  I have never in my entire life delt with such a dishonest horrible company as Xfinity.
