Unauthorised debitorders

I joined on 25 July 2019. The normal debit order of R449 went off on 26 August 2019. Then a few days later another R200 debit order was requested. The bank returned the debit order. First, an authorised debit order for R200 claiming I switched between gyms. Which is not true. Then I have promises of callbacks for admin Dunea and marketer Greg, but of course, nothing happens. Then I'm phoned last Friday to say they are sorry, it was a mistake and it is fixed. But then she sees my account still shows the arear amount of R200. She would call me back on Monday. It is now Thursday and of course, no calls. Banking costs for that authorised debit order is R30.50. I want it back and my account arrear must be adjusted to 0!
