Unfair termination conditions

My wife and I joined Planet Fitness over five years ago. I wanted to terminate our membership due to Covid 19 and the fact that we were both hihg-risk. I had not been informed that our gym was now open and only realized that when our debit order went off yesterday. I phoned customer services today to cancel. The person, Arde, was only interested in the one-calendar-month notice period, which, according to him, meant the end of October. He did not even ask me why I was cancelling. Furthermore, he could not cancel my wife's membership even though she was right next to me. My wife had to make another call. This is utter bs. Now I have to pay for an extra month because I didn't know they were open. If this is the level of customer service at Planet Fitness, I want nothing to do with them in the future. On the off-chance that they want to respond, my ref. no. is PF***.
