Account Representative just cancelled my policy effective immediately without my consent

On a call with an account representative asking about potentially renewing. She said there is no promotion and that my only option was to keep to the current one with a increased rate from $65 to $110. I told her to cancel my account at the end of the bill rate so that I don't get charged the new $110 rate. She went silent on my and then told me she cancelled me effective immediately. She then tried to reinstate my account again with a $70 rate, which I responded that is not okay that I will be charged at a higher rate because of her mistake. I requested her to send me to her supervisor/manager and was told that I couldn't talk to anyone. Upon saying that what is being done is NOT OKAY, she hung up on me. This response is not acceptable in any way shape nor form. Tried calling back a few times afterwards to no avail, so now I am stuck with a cancelled policy and apparently my only option is to reinstate my account at a higher rate because of this lady's mistake. Can someone from Xfinity resolve this situation?
