Bad service AGAIN, can't even do a contract with no issues

Once again Planet Fitness has done somehow managed to get it right that i am unhappy with their service :( I received an SMS at 9:59am saying the following: Due to technical error, Planet Fitness - Vitality activation did not occur in June but has now been activated. Please note you will be debited on 11 July 2018. Firstly i signed for my contract and paid the R900 on 28th June 2018, how is it that i am supposed to pay for June when i actually signed up for July? The ONLY authority i gave Planet Fitness to debit my account was for the end of July!!!!! When i call the "call Centre" Cassandra Mathe helped me, she just said and quote "there's nothing we can do as the debit order has already been sent to the bank"REALLY!!!! Sadly something went wrong with the communication from the club to head office or vice versa but i would like this to be sorted out. I am NOT going to entertain issues from Planet Fitness Douglasdale again. Very disappointing to have give them another chance and absolutely nothing has changed :(
