Bad service, unauthorised debits from my bank account

I joined MoiMooi on November 13, 2017 for 5 treatments at R399 a month, a R200 joining fee with the first month being free. They did not explain that a month meant from the date I joined to the end of that month so I lost out on a number of treatments. The R200 they debited immediately and the R399 on 15 December 2017 (note that my debits were supposed to come off the last day of the month). From January 2018 I was debited R499 which I was not advised but I saw in the contract whatsapped to me after I agreed telephonically, that they increase yearly in January. I don't think this was exactly fair as I was hardly 2 months with them. I tried to get all 5 appointments after but I could never get weekends almost. Then on 31 May 2018, I noticed 2 debit orders go off- one for R499 and another for R200. I called and was disconnected numbers of times so I emailed and a gentleman called Joshua called and escalated this, or so he said. He did ask why I just don't take an extra 2 treatments so I told him how can I if I hardly make the 5 appointments per month. Months after this, after many complaints, I was still not refunded and to tell the truth, it is possible they have done this before and after May as I never check my bank statements but did so because I needed bank confirmation on 31 May 2018. They changed the system and I had no appointments during August as a result of this, except for the one where I booked telephonically and the other where I walked in with a colleague which I had referred. I complained then to the receptionist who escalated on August 24 and I finally got log in details that said I was a new user. I could by this time book nothing as everything was booked out. On September 3, I sent an email to cancel my membership and refund my R200 (which I know of) as there were no appointments available for the whole of September 2018 . Phumla Siko emailed on September 13 to say that they were sorry to see me leave but that the membership will only be cancelled 20 days after the last debit order has gone off. 28 September 2018, R499 went off my account. I had to pay to do my hair, massage and wax treatments elsewhere!!! This is bad service and they owe me money. I am furious as I can't be paying for services I did not receive and have extra monies deducted from my account on top of that.
