I WANT MY MONEY MrD

I placed an order on MrD, Steers Dobsonville mall. I ordered a meal worth R270 (cheese burger comes with fries R106 and a Big something with fries R163..) and then the driver came and to the shock of my life gives me a small paper back thingy from McDonalds... How do I order at STEERS and McDonalds gets delivered?! The driver obviously didn't know anything and didn't know what to do!!! The Mcdonald's was a big mac, I don't eat the big mac! I want my money all of it MrD! and I'm ddeleting this ****** app because earlier this year I tried to order and got debited but they said that no order was placed even though money was taken from my account and that I should handle it with my bank!!! I WANT MY MONEY!!
