Problems from day one!!!

I join the gym and they charge me too much on 1st payment. The following 3 months they deduct money on the wrong date as what I requested. They tell me it was changed but then they deduct it again on the wrong day of the month. Then due to this matter every month my bank deducted an extra R116 from my account under reference \bill not payed"because planet fitness captured the wrong date. I go to get feedback on this matter and I'm still waiting and already requested my cancellation! Very bad service!!!"""
