Terrible service from Vuyo at Nandos Tokai

My family and I regular use the Tokai branch in Cape Town, due to the excellent service we have received, visiting two Sunday lunches a month. However not having gone for about 2 Months we decided to go today. We ordered a full chicken meal with 4 sides sharing. After waiting for approximately 15mins we were informed that the Chicken would be another 35mins, the branch was basically empty, the reason given, was a late staff member. The chicken arrived 40 minutes after the order was placed. As soon as my wife bit into the chicken she noticed that it was off. I called the manager (Vuyo) over and explained the situation expecting a simple solution, however Vuyo insisted on fetching the batch no. which showed a sell-by date of the 2/08/2022. She explained that the chicken was for the previous business day. so it should be fine. however when I asked if the the late frying had left the chicken sitting, she now showed me a later. dated batch no. which made no sense. When I asked to if she could not just replace the chicken, visible angry she stormed off with no communication, I followed her to the till and explained that we had an appointment and was running late and wanted to be refunded she returned only the money for the chicken, we had to ask for containers to collect our sides because had eaten from it, the chicken however we returned untouched. I explained that the service was poor and that I wanted to address it with management. I asked asked for her name which she would not give, However Stephen Engel was extremely helpful and gave us her name and apologized. Vuyo sarcastically told us to contact the call center if we had a problem. When we called the center Vuyo had given a pre-emptive call and told the center to expect a hostile call from us, their wording to the center not ours. Shock and horrors Mr Vilakazi at the call center seemed irritated when we asked for his detatils as a reference which he rattled off and then dropped the call with us hanging, what a absolute let down and a disservice to Nandos who is our " Healthy chicken" option and whom I know would not endorse this type of service. therefore I felt compelled to inform about this extremely unpleasant event. An apology from Vuyo would be most welcome.
