Travel Advantage Network review: Service fee on a canceled account

This is in regards to a fee of $436.95 that I am disputing I have been with this company for decades. My plan ended on 8/30/25. I was told I could not cancel services until my last vacation was completed which was on 8/30/25. The company was closed for a 3 day holiday so on September 2nd I called to cancel services as of 8/30/25 and was not authorizing the service fee that would automatically bill on 9/1/25. I checked my bank while waiting for the office to open and was told the fee had not billed so I called and spoke to a representative explaining my situation and was told it had not automatically billed on their end either and would escalate it to try and get it stopped and she closed my account. She informed me if it did bill I would be credited within 39 days. The next day I got an email from her stating they could not stop the payment from billing on my closed account and nothing they could do!
I asked to speak to a manager who then told me the other representative was new and basically said yes you will be billed for an entire year. It is September 1 and I will be billed for the next 4 months on a closed account. I felt the manager was extremely condescending.
This was extremely upsetting for me to be treated this way after being a loyal customer for over a decade with no complaints.
