Bad Attitude and service

Saturday went to Chicken Licken store (Jubilee Mall) , I bought 1 Chicken Inn 9 and 1 hotwings snack, was given a bad attitude by the cashier who was assisting me. I placed my order and paid with R200.00 when I had to be given my change she chose to hand it over to my partner, it didn't make sense as I was the one who paid not him. i then protested to that she handed over the slip and the change, on the slip it showed Hotwings snack of R20.00 not the Chciken Inn 9, my order number was 20292 I immediately asked her why was the transaction of the Chicken Inn was not included yet I paid for it, she proceeded to assist the other customer and then I was given another slip order 20294 which is very strange, for peace sake I waited for my food and left. Today I called ********** 255 and spoke to Vusi and relayed everything and he asked what is the problem there. I got very upset and told him not to test my patience he then said I must come to the store and point the cashier out. this store has a serious problem of customer service. The cashiers are very rude and they get away with it , and Vusi just confirmed it now. He was very passive. I am currently in JHB but I will drive back home on Thursday. The lady didn't have a name tag and I don't understand why should i point her out while it is clear she didn't want to be identified. So Chicken Licken doesn't give their employees name tags?
