Chat agents who blatantly lie? Really?

So to make a VERY long story short..my bill jumped up in cost (yet again) and i was trying to get it lowered. I can get 2 yrs of 1G fiber optic + Hulu Live for 150 total. 

So, after an hour on chat, he tells me that due to my being a long term customer + good payment history, he will give me a 'loyalty deal' and drop my bill to $150, and everything was set and noted on my account...and all i needed to do was call this phone number he gave me after 2 hours to give verbal conformation.

So i was pretty pleased until i called and found out the number he gave me was just the main Xfinity number.  It wouldn't even connect me to a human, and while i was on the phone it kept sending me links to re-enter chat, so i finally did.

I talk to the next agent for a while, i explain everything....and he just starts trying to pitch me different deals.  He kept dodging and evading my questions. I finally stopped him and asked him straight up if he could see anything on my account regarding what the previous agent told me, and he just flat out ignored my questions.  

At this point i was beyond frustrated and running out of time (had to pick up my daughter).  I asked him for a direct number for a level 2 person or Manager.  He gave me a numver and disconnected, after which ibrelize he just gave me the basic XFinity number that starts you all over again with a bot.

This is just awful service, and I can't believe that Xfinity is cool with having their agents blatantly lie to customers.

Do any Xfinity reps monitor this forum, or does anyone have a direct contact with Xfinity management?
