Deeply unsatisfied customer

Hi, I started my contract with Virgin active Kingspark Durban last year September 2025 and my premium was R565, but instead of debiting the agreed upon amount, they have been double debiting me R1000 each month. I have tried to get in contact with management for the last 4 months with calls being ignored .i have been told many a time that my issue will be escalated to no avail
