BAD CUSTOMER EXPERIENCE

I JOINED VIRGIN ACTIVE CLUB IN 2021, THEY HAVE BEEN DEBITED R480. FROM MY ACCOUNT UNTIL NOW WHEN I ASK THE CLUB TO STOP DEBIT ORDER FROM MY BANK ACCOUNT BECAUSE OF OVERDRAWN. THE PAST THREE MONTHS I PAID VIA THEIR LINK. I CALLED THEIR CALL CENTRE I WAS ASSISTED BY DIFFERENT PEOPLE I ASK THEM TO MAKE CHANGES ON THEIR SYSTEM AND THEY SAID THEY CANNOT REMOVE DEBIT ORDER HOWEVER MY MEMBERSHIP WILL BE DEACTIVATED ON THE 7TH OF EVERY MONTH. I PAID MY AUGUST MEMBERSHIP. NOW THEY ARE TELLING ME THAT I OWE FOR SEPTEMBER BECOUSE THEY CHANGE MY DEBIT ORDER FOR THE 15TH OF EVERY MONTH THEY EVEN CUT OFF MY ACCESS FOR AUGUST AND I PAID FOR THIS MONTH, NOW I ASK THEM TO CANCEL MY MEMBERSHIP FROM THE 1ST OF SEPTEMBER THEY SAID I STILL HAVE TO PAY FOR SEPTEMBER EVEN IF I CANCEL. PLEASE RESOLVE THIS.
