Dishonest Xfinity changed my account without my consent. Now I pay 50 more a month with less features. My account reads consent override

A dishonest customer rep changed my account without my consent and now I pay 50 dollars more a month, have less DVR space, lost Netflix and other features.  Xfinity says there is nothing they can do about it, even though several people have said that what that rep did was misleading and dishonest.  I had a bundle package with all the premium channels, DVR and Netflix included.  Xfinity sent me a new updated modem and I was having problems connecting it to my camera system at home through Wifi so I called customer service.  They were not able to fix the problem.  The rep noticed I had a landline and said I can have that landline connected to a new cell phone that they would give to me for free and that my bill would actually go down by 20 dollars.  She explained that Xfinity was allowing their landline numbers to go to cell phones.  She did not mention anything about changing my bundle package.  When I got my bill not only did it not go down it went up in price substantially with less features. 

I called customer service again, that rep said the other rep shouldn't have done what she did and that I should go to the Xfinity store.  I went there they checked my account.  The rep said they need to see if I gave consent and on my account it had consent override on it (of course I did not consent to pay more for less features) so they got their manager.  The manager looked at it and said that it shouldn't have happened yet if I agreed to have my landline go to the cell phone that would change my account.  I found out I had a grandfathered account and they say I can't go back to it.  No one mentioned that or that I was changing plans period.  They mentioned that they have the conversation on tape.  At first they wanted to listen to it then they said they still couldn't change it back anyway so why bother listening to it.    The original rep said my plan would not change yet it did.   They said the price would go down, yet it went up. Now HBO, Showtime, MGM, Netflix are a la carte on my bill when they were included in my old plan that's a 50 dollar increase.  I also lost DVR space and programming I had saved.  At the store a rep said that earlier someone else got the landline to cell phone deal and they had their account changed too to their surprise. Xfinity knows what they are doing and I believe it was on purpose to get me out of that bundle I was in.  I'd like to have access to the phone conversation because I did not agree to these changes as it says consent override and it was dishonest.  I believe this is fraud or some kind of bait and switch.  I am very disappointed and I'm ready to move on to another service.  I heard the horror stories that other people have gone through with this company and now I'm seeing first hand how this establishment treats long time customers.   I'm asking them to make this right and have my previous account restored or make new one that has the same features and price. I will go to whatever consumer site and seek counsel if need be.   I hope Xfinity would do the right thing and act in good faith and be honest with their customers treat them with respect.
