Cancellation of club membership

Message: I have been trying to cancel membership with Platinum Leisure/Astral Group since 6 April 2017. They acknowledged my email and I was told the cancellation was being processed and it would take 30 working days. Debit orders still go off my account every month and they keep using different references such as Emerald, Africo, Example:Debit Order R79.00 CONYBEXREC.I need this cancelled immediately and be refunded my money for all debits after cancellation email. I called ********** 001 today and held for 15min the voice kept saying I was the 1st in the queue but no one answered until I dropped. Frustrated!
