Internet plan change confirmed but never activated

Please just honor the plan that was agreed to on a recorded line. 
why do I need ro go start another message .  It’s as bad when I call and each person I talk to is brand new and I need to explain the issue over and over again. Why is this the way customers are treated? 

Fast forward two months from this rate change on my account and now I am all of a sudden over on data and paying $10/ gb… no option but to go to att.

thanks.

I am still trying to resolve the issue.  It was confirmed that the deal offered was accepted by phone and PIN code however i am told there was no confirmation link? sent by Xfinity and therefore i do not get the deal offered.  Really ?   Instead, i am being offered more expensive deals.  Is this how Xfinity does business?   Google fiber is installing in my neighborhood as we speak.  Will not think twice about switching internet providers should i not be given the plan offered, and accepted by me, to date.   Whoever reads this from Xfinity please  make this happen and just send me A message saying , “we are sorry for the inconvenience, you are right!, and we will honor our commitment to you , backdated to date of call and verbal and PIN code confirmation.
