******s who refuse to provide feedback

We joined Planet Fitness Moreletapark on 31 August 2020. Membership fee R399 plus a black tag for R99 extra. We were told that we only needed to pay the tag activation fee of R224, which we swiped for at the branch. We were told there is no joining fee because we are on Discovery vitality. On the day of our first debit order they took too much money. Two debit orders went off one was R399 and the second R568. Where is this hidden cost coming from? I sent an email to the branch on 02 October, I received a call on the same day from the Sales Manager at the Moreletapark who told me that we were not supposed to be debited that much. He also told me that he has escalated it to the customer care department and has CCed me in the email. I still have not received any email. I followed up about 3 times via email and I tried calling as well but they just told me the sales manager is not available. I was promised that he would call me back and he did not. They refuse to provide any kind of feedback. They are robbing us and their service is **********!!!!!
