Formal Complaint

I recently joined Xfinity last month. While on the phone with the agent, they told me a set price including promotions. So I agreed to it and switch carriers. My first bill came in and it’s higher than promised. I spoke to a new agent who, by the end of the chat, said I was set and they have fixed the issue. I confirmed with them and asked if I would get the rate I was promised and it would last the first year of the contract, like I was promised. They said yes. Later that day I checked and saw they fixed some of the bill amount, but not all. I called in again and was told it was fixed and it will be the same moving forward at the rate I agreed to. All was fine until recently I got the bill statement for this month. IT WAS HIGH AGAIN! I called in and the new agent tells me what’s on my bill and now there is nothing they can do, it’s correct. Even after checking the notes and call. 4 agents and all different and now the bill is what it is, higher than promised. So I was lied to multiple times. I asked to speak to a supervisor and they just kept repeating the bill and said it is what it is, it can’t be changed. I asked about the call, they said they will review and talk to the agent, but the bill won’t change. I asked how I can get out of the contract because I was lied to and should switch carriers and was told I have to pay the whole thing (phone and plan coverage). CRAZINESS! The call ended, and now I am in a contract I didn’t agree to and no one to help. I need the money I have for additional bills for me and my family. I come here to file a complaint and follow the directions the AI said to do, but the directions are not correct. I need all of the notes and calls reviewed and my bill fixed to what I was promised when I signed up. I have pictures and can show what I have, I have names, dates and reference numbers as well. This is not good business and should be sent to the BBB to review as well. Customer guarantee and we come first, but can’t help when YOU make a mistake.
