Planet Fitness Wanderers - poor poor customer service

I signed up for gym membeship for my children at Planet Fitness Wanderers. Planet fitness over debited my account for the period October 2024 to December 2024. I tried to address this with the sales consultant Simon, Sales Manager (Granville) and Branch Manager (Dameon Van Wyk). It was further escalated to their cusotmer service platform. To date the above staff members failed to address and managers hwve not responded. I've resorted to cancelling all debit orders and the over deduction has not been refunded. Very poor service for supposedly a reputable gym. A simple refund / credit of my account could resolve this for the debit order to be reinstated. Horrible customer service.
