UNHAPPY CUSTOMER!!!

I went to Nando's horizoview drive-thru on Friday around 6pm to buy a full chicken as usual I asked for extra sauce. The lady(not sure of the name) at the window was so rude telling me how I'm taking a lot and how I shouldn't explain a lot of things. Decided to drive thru spoke to Lerato where you collect your food,I asked for managers name said it was Masilo. Called back to speak to Masilo as I was driving back home than a "Ndimthandile" answered the phone and said she was the manager. Told her my story and to my surprise she said she could here from her office as the lady was screaming at me but to my shock she didn't bother to come out and reprimand the lady. I said to her I want an apology from the lady which till this day I haven't received. Ndimthandi called me back on Saturday and said to me I needed to explain my ''story,'' I refused and said I had already explain to her yesterday so I was expecting a call with solutions. So Nando's do you guys train your stuff or you are just running a ****a shop there. I'VE NEVER BEEN TREATED LIKE THIS AND YOU WILL NEVER TREAT ME LIKE THIS AGAIN. NXAAAA!!!!!
