Bad service

At about 20:40 on the 26th of December 2017 we stopped at Steers in Kuruman (Northern Cape). We ordered for myself a chicken burger with bacon, feta and quacamole and for my boyfriend an original king steer burger. When we eventually got home we realized that we had received the wrong order. We received an ordinary small burger and another burger with ribs on. We immediately phoned the shop and asked to speak to the manager. The lady who answered the phone said that she is the manager. I said that we received wrong food and that we will be there shortly to exchange it. She said that they are closed and that i must come back the next day. I explained that we had worked 14 hours straight without stopping to eat and that if she wanted to only exchange the food the next day, then she must pay for it the next day aswell. Without excusing herself she mumbled something to the effect of "free meal" to someone in the backround. Another lady came to the phone and I again asked this lady if I could speak with the manager and she said that the "bestuurder" is on another call but she is also the manager. I explained the same story and then i was placed on hold for several minutes. We agreed that they would fix the food and we'll pick it up. When we eventually got back to the shop we were greeted by yet a different manager who looked at the food and slip and said to the staff to make the order. The shop was already closed and all the staff were sitting around. Whilst preparing the order the kitchen lady shouted to the staff sitting in the fronthouse to explain what is supposed to be on the chicken, bacon, feta, guac burger. We got our order and I double checked that we got the right order this time. They forgot the guacamole. At this point I was so tired and ticked off that I just smiled sarcastically while the staff members were laughing and the "manager" fixed the order once again. When we left we got a very sarcastic "lekker aand" from one of the tswana staff members sitting in the fronthouse. The laughing party of steers staffmembers followed us out as they were also leaving for home. The worst part is not that we had received the wrong order, but the unproffesional attitudes of all the staffmembers of Steers in Kuruman. PS, the few pieces of feta cheese I found on my Chicken, bacon, feta, gaucamole burger had gone off. We are so upset with the unbelievable experience we have had.
