Debit order after cancellation

I sent an email to cancel my account - multiple calls and emails later they finally responded. They tried with customer retention however I told them I am still looking to cancel. They went ahead. I haven't been debited since the gym has been operating again (because of Covid it was shut) and now all of a sudden they debit my account. This is absolutely ludicrous!!!! When you call the number they say they'll transfer you to the accounts department, but then make you wait on the line for 10minutes until they just hang up (clearly we have to play a game of "who will hang up first"). Refund me my money!!!!!!
