Gym Membership Cancellation

I would like to express my frustration at being harassed by Gym Company by Juliet E Garira, Liezel Heubner, and Desiree. My Gym Membership expired in December 2023 and I have informed them now on several occasions that I do not live in the country and hence I have not attended their gym and honoured my payments to the close of the contract. Fair enough there is a clause in their ************ contract that you must send a cancellation. I have done that and made payment for the arrears and still today they are harassing me with emails with further invoices and debiting my account. I have seen other people complaining of the same thing and this ladies/company needs to be brough to book for this nonsense.
