Terrible service at Chris Hani Steers

Yesterday at 16:51 I placed an order for 2 as'phande meals and one king steer burger. An hour later the driver dropped off the order, my older son picked it up and paid. When he got into the house he was busy unpacking when I realised it was a wrong order. I told him to rush outside to see if the driver was there, but he had left. I then proceeded to call Steers numerous times, I'm sure I must have tried 30 times. I even tried on instagram dm. We waited about an hour and a half hoping that someone would see the mistake. My kids and I were hungry by that time and seeing no other we had to eat the food, cold as it was due to loadshedding. The chicken was horrible to say the least, they hardly ate any of it. At 8 or so I only then received a call from Steers Chris Hani to tell me they saw the mistake. I told them I ate the food already. They told me the people who has my food didn't eat anything and since I ate the chicken I need to pay for it and they will bring my order as well. I could have refused but I don't said it's okay fearing the driver's money will be deducted. I specifically asked them if they gonna make the food fresh or just gonna give me the same order that's cold, the manager said they will make it fresh. I told them to call me at 8:30 that's when I will have money on me. Indeed the manager called at 8:45 and proceeded to send the driver and I paid for the chicken. When I opened my order,and there were only 2 as'phande burgers instead of 4 and to top it off, the burgers were dead cold only the chips were warm. I called back the shop and the manager was rude and refused to acknowledge my complaint and insinuated that I was lying. First of all by the time she picked up the call dhe already sounded bored cz she kept making mm sounds in a bored manner. I do not appreciate the treatment I received especially since I was so understanding of the situation they messed up amd paid when I wasn't supposed to. I am very upset by the treatment I received from ur staff, ur manager to be precise. She doesn't know customer service, I dont know how she's a manager.
