Disgusting attitudes vs Digusting food?

We purchased a family meal as we do every single month from this mochachos Carlswald and this will sadly be the last time we will purchase from here. I must say that since the new owners took over the place has gone to the dogs. The staff's attitudes are absolutely disgusting and I am not surprised since the manager himself has such a horrible attitude towards his customers. We purchased the meal and was fasting this particular day so we only opened the food that afternoon and when we did we found that the chicken was extremely dry and tasted like old chicken. The flavor of the chicken was incorrect and the chips was as it was fried 10 days ago. Now, I am a customer and I paid my hard earned money for my food not to have my husband go into the store and be degraded and laughed at by your staff! The manager himself says nothing is wrong with the food( picture attached) He then goes on to tell my husband how he is only replacing the meal because of the incorrect flavor! We have been purchasing mochachos for years before this manager was ever in this store so we are well aware of how our food was supposed to be. You then have a training cashier who messed up the order and instead of apologizing stands up Infront of the manager and argues that she is right and that my husband who has been placing the exact same order for over 5 years, every month, is wrong! What kind of **** show is this place gone to? This place used to have a 5 star rating and now sitting at 3 stars and will most definitely drop more with that *********** manager running things. After reluctantly replacing our food, the staff then patronize my husband further by making comments back and forth about the flavors off the chicken which he ignored they then proceed to start taking in Isizulu not realizing that he speaks it too and when he asked them to repeat themselves the guy says " I am not saying anything to you" and they all start laughing again! We paid for our food, we didn't get it for free, your staff messed up our food and then proceeded to humiliate my husband for asking for what he paid for! We wonder why places close down so fast, maybe get staff that are serious about doing their jobs and a manager that leads by example.
