Wrotten chicken burgers sold at Steers Southgate

I went to Steers yesterday to buy Wacky Wednesday at Southgate. I placed my order and asked how long it will take and was told 10 to 15min.I told them it's okay I;ll come back later. When I came back I saw ready orders and went to ask if mine was amongst them and was told no. I took a seat and waited. I saw my oder was preparing #261 but this order never moved from the 1st in que. I did not say anything but noticed that I was being watched from the staff at the back and in front. I kept quiet and waited over 30 min now then out of the blue a lady brought my order to my table without asking my number or anything. I thought it was strange but I was running late I left. When we wanted to eat the burgers my son told me to taste my granddaughters burger and I realized the chicken was off. I phoned Steers 4 times and phone was dropped in my ears when I asked the details of manager she told me she will phone me back. IU phoned again and eventually the lady that answered told me her name is Lebo and she is the manager. I could sense that she knew me coz I did not have to explain she started apologizing and told me to come see her the next day she will give me a full chicken. I told her can never trust Steers again.
