Disgusting food & service

So we visited the centurion mall wimpy this morning for a quick breakfast. We decided to order lunch as it was almost 12. I had the double schnitzel with mushroom sauce, my son had the classic cheese burger and my husband had the triple grill. Within 5 minutes of placing the order, We then received news that there was a family emergency we had to rush, asked the waitress to please cancel the order, she refused and mentioned the food is on the way out. To my surprise, In less than 2 minutes we received our meals. I am totally disgusted at my husbands food.. He was so disappointed, starving and extremely put off. The food had a raw, couchy smell. You could literally smell and taste the sheep! We complained to the waiter, who then called I'm not sure if it was the manager, however it was a black woman with short blonde hair who then replaced the meal. They gave us ****ty attitude, she kept giving me horrible stares and she just stood with the waiter behind us gossiping and making us feel uncomfortable. Anyway, we received the thrill of the grill in less than 2 minutes. I'm amazed how they are faster than a drive thru. My husband was still not happy, the sausage was tasteless, the chicken was pink inside and the peri peri sauce was sour for some reason. We didn't complain as we felt bad and thought the staff would then think we are just being difficult. Also, we were rushing and didn't have time for this. Hence, I am laying a complaint with head office. The food and service is totally disgusting. As a breakfast restaurant, you would expect more smiles and friendly staff. Poor service! This is unacceptable. We spent R480 where as we could have had a lovely meal at spur and would've been totally satisfied with the food and the service. I would like to be contacted by head office. I have my slip available with the waiter and order details
