They stole my money!

On the 2nd May 2020 , I had tried to place an order for McDonald’s on the MR D app. I kept receiving an error as such tried abit later. The moment to it gotten to the “continue to payment” prompt I had received an error advising “technical issues” however there was an automatic deduction of R216.60 out of my account. I immediately went to my order history however noticed that was absolutely no order processed for the R216.60 and the only proof of this deduction was the sms I received from my bank , meaning that this transaction was not authorized by me the way it usually prompts you to. I then sent two emails querying this on the 2nd, I sent 3 emails on the 3rd however still no response, no apology for the inconvenience, no refunded amount either.
