Debit Order for a cancelled membership

Very disappointed in the customer services of Planet Fitness. After cancelling my contract in Feb, then waited my month cancellation, and receiving a confirmation email from them that my cancellation is in process. I was debit ordered again in May (for 2 months) and again in June. I phoned customer services, but they cannot help, I must email the complaint (which I did). So now I have to pay R70 per reversed debit order to get my money back! I am not a member anymore! I do not authorize you to take my money! Fix your system!
