Double charged complain

On the 26th of April I went to KFC in Vanderbjilpark. I made placed an order through a kiosk and I didn't get an SMS or text in regards to my order number. I checked my phone and relizei that the order went in because the money for it was withdrawn. After few minutes they reversed it (payment correction) I then placed another order , however I changed the ice cream I wanted and I got a text on WhatsApp regarding my order number. When I checked my balance I realised they have taken the money they have reversed and the one I placed for the order which I got it's order number and it's meal . Right there I asked for a managed and frankly he was kind enough to hear my story and made me fill up the form however I have still not heard from them or get my money back. I'm not happy!
