Tricked/Defrauded by online Xfinity chat agent - HELP

I used  Xfinity chat to contact an agent to buy a new x15 remote because my daughter spilled juice on of it and the buttons stick. The agent out of no where said he could save me about 15 dollars a month with a special they had. I clearly asked if any of my services would change and he clearly said NO. (I have snapshots of the chat!) He then asked me my cell phone number and told me to click and hit accept which I naively did without scrutinizing what he sent me and it’s hard to understand regardless. He said he would send the new remote in the mail and that was that. I ended the chat happy. Well then my day turned horrible. My first inclination I was lied to/ defrauded by the internal Xfinity agent (His name is Harjeet) was an email from Netflix saying Xfinity  would no longer be paying for my subscription about 10 mins after the chat ended. I immediately picked up my phone and called Xfinity  customer support. The agent told me I was put onto a very basic plan and all my premium channels were gone. My Netflix and other streaming subscriptions were gone also. He couldn’t believe the online agent did this and said there was nothing he could do because I was on a legacy plan and to get me back to all I had 20 mins ago would cost me an extra 150 dollars a month! Absolutely insane. I told him I have the transcript with the agent and read to him the interaction. He could not believe it and said he felt horrible for me. He then transferred me over to the Comcast fraud department. I spoke with the fraud agent who stayed on the line and transferred me to customer solutions and explained the situation. That person kept me on the line a half hour only to tell me there was nothing she could do other than charging me an extra 150 dollars a month to get me to a comparable plan with all the extras I had . She then transferred me to customer loyalty department. That agent was very understanding and said they would restore me to my prior legacy plan but that it would take 24 hours. He also said he sent me an email confirming all this. Well it’s been 6 hours and I never got an email and now I’m doubting anything was actually done. I am so upset and I feel like I have been criminally wronged and this wasn’t a simple mistake my Harjeet the chat agent who did this . I feel like he may have compensated for tricking me into switching my plan and I have the conversation with him which I’m happy to share with any internal Comcast/xfinity  persons or external regulatory authorities.
