Terrible customer service

I have been trying to cancel my Fourways gym membership since beginning of May '24 (more than the 21 days notification guideline) and have sent several emails with the club manager on copy. I have not received any correspondence with regard to my request & yet I am still being debited each month. I want my membership cancelled & a full reimbur*****t of all the debit orders that have gone off from May '24. The club is very engaging when signing you on, but silent when you want to freeze or cancel your membership
