Bad restaurant to order from.people shouldn't waste their time. They are even playful

The worst experience I received from this restaurant. I am so dissapointed and I am still waiting for my refund. I spent R280 and till this day I didn't get my money back. I placed an order for 5 dunked buckets of 1. Firstly the order took time to arrive and by the time it came it was totally wrong. I received 4 streetwise 2 paps. The slip on the packaging was of my order yet inside it was totally different. I called them about this and the guy on the phone first said my order is with them, they mistakenly swapped slips. Then he asked if there's anything I can do which was none cause I stay far to go get it as he stated that the drivers have already left. He then asked to hang up so he can ask the manager on what to do. A few minutes later he called back and said they will cancel the order and get me a refund and that I should use the wrong order. I asked him if they sure about everything and he said yes. Until this day no refund..when I call them using my number they don't answer but if someone else calls on my behalf with a different number they answer.. If this is how they treat customers then wow. Can I just get my money back and I will never ever order from them.
