Xfinity assistant/billing issue

I spent an entire day on xfinity assistant only to get [Edited: "Language"] over by an agent named "Chris". I went on xfinity assistant for help with an issue on my bill. The agent then told me by the end of our conversation he would be able to save me money. So I decided to hear him out (this is not even why I went on there). He ended up asking me what channels I watch and I specifically listed them to him. The offered me a deal that was $20 less a month with increased internet speed. I asked him about losing any of my channels he assured me that I would not lose anything and that all I would be getting was benefits. So I agreed. He also told me that getting and paying monthly for an ipad was part of the deal. I told him I dont use tables and did not want to pay for an ipad monthly. He responded (and was clearly getting annoyed with my questions) saying if I removed the ipad, the bill would go up because it was part of a "promotional deal". So I agreed. The second my system updated after going through with this, I lose the channels I watch that I specifically told him I didnt want to lose. I was livid. I went back on assistant and connected with another agent. Who apologized and said yes that "Chris" had changed my channel lineup to a lesser plan. I also told him about the ipad. Which he also apologized for and said he would remove for me. He ended up telling me he was putting my old channels back on and removing the ipad and my bill would be $20 less than the "deal" I was given before. He sent me the link for approval, which didnt work. After that he disconnected. It was then HOURS of getting connected to agents ever 2 mins. Each on apologizing and saying they were reviewing my chat and would finish helping me. I kept saying over and over i just need this approval link. They kept telling me they were sending the link. But none ever came. There was obvious some serious issues on xfinity assistant. I had to sign off I couldn't wait any longer. Now every time I try to go back on xfinity assistant it says there are unusually long wait times and I cant chat with an agent (even in the middle of the night). When I clicked schedule a call back the date I was offered was in a week! This is absolutely insane. And now im sitting her paying for an ipad I dont want and I have lost channels that I watch. I am beyond mad about this situation and the issues on xfinity assistant are out of control and seem to have come at a convenient time. I have been trying to reconnect since Saturday and it will not work. I need someone to help me finalize what I agreed to!
