Completely lied to for personal gain

The person I spoke with, she said her name was Sara [Edited: "Personal Information"] at [Edited: "Personal Information"]. The only reason I called was to update my autopay information. Sara Joseph informed me that my contract needed to be renewed if I wanted to keep the $50 price. I told her it's a 3 year contract and it shouldn't need to be renewed. She stated that it "ended early" and "think about this calmly, wouldn't it be better to pay $100 for November and then it will go back to $50. I told her no that's not right, it is $50 a month for the whole 3 years and I have about 2 years left. I asked to speak to a manager, and she said that he is not available, and that if I don't renew it today, that my bill we will be $115. I told her "I only called you to update my autopay information, so if there is any issue I will talk to my local office. I immediately went to Xfinity in Lynchburg, VA. They looked up my account and assured me that my contract is up in 2026 and I pay around $50, and this [Edited: "Personal Information"] did not give me the right information.
