Recent Plan Change Not Reflected

I have had the same problem. I have been a customer since before it was Comcast. I was promised a price for a plan by phone on December 26, 2024. When I did not receive the prompts to accept the agreement I waited to see if the changes to my account had been made. When I saw the higher price, I again called the company and was told they showed no agreement made. I told them to pull the recording of my phone call where it was promised to me. It is now January 21, 2025 and they are telling me they have not received the recording yet! In the meantime I have had to pay the higher bill. This is the second time this has happened to me!! The phone tree is infuriating! If I wanted to text or use AI, I would have done so. I had to go through the menu 3 times before I finally talked to the unhelpful agent. When I tried to use the Xfinity Assistant previously, I was told they could not help me. This is not a way to retain customers, even the ones like me from the 1980's!
