Incorrect billing not sorted out

We have subscribe my daughter at virgen active Richardsbay branch on a special that tbey had in Desember 2017 on a black friday. The consultant Linto was very helpful to get my daughter subscribed and explained everything and also that the first debit order will only be on the end of January 2018 with the special. Everything has been done and she was up and running to start her new membership with Virgen active, then came end of Xecember and they tried to put a debit order tbrough. I phoned Linto and ask him about it and he said we must not worry he will sort this out. She went to the gym several times although sbe had trouble to get in because her card showed that there is a payment for December missing Linto was everytime full of promisses that it will be aorted out. January 2018 payment went off and for a week al was well when all started al over again but Linto was not working there anymore and so i spoke to some people at the gym everytime the same story. Every time that my daughter went to the gym there was a problem. The week of the beginning february i went to the desk and ask them when will this problem be sorted the lady called the admin lady and she promissed me that she will log a call and get the errors cleared. On the 12th february when my daughter got to tje gym they said she will no longer be able to gym before the instalment that is overdue for december is paid. On the 13th i went to the gym once more and ask them what are they going to do aboit it because my payments is up to date and when the lady at the desk checked for me the admin lady did not even log a call or anything has been done to get the problem solved. This is totally unaceptable for a huge and famous gym lime Virgen active and i would like to get help to sort this problem in order for my daughter to go to the gym without getting humiliated each and every time.
