Zone fitness Is still taking my money!!!

I have honestly had it with this *******. My contracts duration had ended in March 2020 already, however debit orders proceeded because no cancelation had been processed!!!nothing of which had been explained in the beginning. Where is the communication??? I refuse to pay anything that is still billed to my account, apparently I am in arrears of R310 but they have been consistently charging my account with attempts of debiting me which amounts to over R500 everytime its 110 they take up to 3 times in the month. Cancel this contract and stop the debits. SUE DUIMPIES has made contact with me once and never again!.. Highly frustrated with the lack of service and communication!!!
