Big 10 Network and irrational contracting

Boy has this been a month with Xfinity for me.  Let's start with my first issue which stemmed all my issues...

Back in mid-August, I found out that the Big 10 Network was not on our regular channel lineup for some ridiculous reason. In case you don't know, the Pac-12 collapse (channel removed) and many Pac-12 teams went to the Big 10 and Big 12. The channel lineup now didn't include local college sports in our area. To get this channel, we now had to add the Sports and Entertainment package (add'l $$).  Didn't want to but had to so I did.  Come to find out, closer to game time, Xfinity has BLACKED OUT those teams sporting events and I still can't watch them.

Here's where the decline starts...

With adding that package, the chat person said that he can upgrade our internet and save us a bit of money.  Great!  Fast forward a few weeks later and now that modem we got didn't support work VPN (which I found is a whole other issue through reddit posts)!  I hit up chat support and that person said that we can pick up a new modem to see if that will work.  Fine.  I have to approve his access and, come to find out later, I'm renewing my contact again and starting a new term!  Just to get a replacement modem (I'm not asking for a new contract!)  I asked this person if it would change anything on our plan and he said no, which was a flat out lie.  A change to anything on my contract is a change.  Anyway, we pick up the new modem and it seems to be going OK so far.
That evening, we go to try and watch cable tv on one of our boxes and receive an error code.  I hit up chat again and am told that the box is inactivate and must have happened when I picked up the new modem (HOW?!).  To be able to activate it, I'd have to acknowledge my plan again and thus restart a new contract!  JUST TO RESET MY TV BOX WHICH WAS A MISTAKE THAT XFINITY MADE.  Also, I'm told our bill went up $10/mo between these new contract agreements when all I thought I was doing was getting a new modem (faulty modem, not my fault) and trying to reset my tv box (which I declined to sign a new contract and it's still not working).  Once again, before I stopped moving forward, I asked the chat person if anything to my plan would change and they said no!  Which again, lie!  When I asked if my contract term would change, they said yes!

What can be done here because, after using Comcast for over 20 years, I feel so completely done and straight up lied to.
