Worst Customer Service Experience

I am very disappointed with the way that I was treated by the manager at KFC Eloff Street Opposite Ghandi Square by the name ANDISWA. She is very rude and her customer service is very poor to say the least. Last week I went to the restaurant to purchase the Tuesday special and I was told its not available, I can only purchase that with chips for R85. I then asked the cashier why are they advertising for R65 (mind you that would be false advertising) the Manager who was standing next to the cashier and obviously listening to our conversation jumped in and said to me that differs per store and their system only has the one for R89. I paid that amount and waited for my order, while waiting I noticed on my slip it was written “Up sell”. I work in the sales industry and I know the meaning of upselling. I collected my order and left without saying anything. When I got home I posted on their twitter on the post that says the additional R20 for chips is not compulsory and there was no response. Fast forward to yesterday the 12th of March 2018. I walked into the very same store and I asked for the R65 rand meal, I was told the very same thing and I clearly stated to the cashier that I wanted the R65 meal and that she must not “up sell’. Seeing that I know what I’m talking about but on the other hand she is working under instruction she referred me to the manager, who was very ******** and rude (this is the same manger I spoke to last week). I tried to show her a twitter post that but instead she turned to the cashier and told her to serve other customers if im not buying for R85. I asked her how is she going to attend to someone behind me before finishing with me she rudely said if I have a problem I must call customer care. (does this lady know how much it cost to call a premium rated number per minute) Fair enough I call customer care and I speak to Nomfundo and I explained to her, she promised to call the store and ask the manager to speak to me about 10 minutes later there was nothing, im still standing there like an idiot. I called again and I spoke to someone else who’s service was very poor I don’t even remember her name. She even hung up on me. I called again and I got hold of Nomfundo again and she told me she tried to call the store 3 times they not picking up. She asked me to hand over the phone to the manager and she blatantly refused to take the phone. Nomfundo promised to escalate and she sent me an sms with a reference number. As much as I used over R75 voucher to lay a complaint of a R65 meal, Nomfundo was helpful. I walked out of the store and called the store just to make sure they were intentionally not picking up, and guess what, the phone rang to the dead. I sent a direct message to the KFC’s twitter account and until this moment I haven’t received feedback. I am not happy with the ANDISWA’s behavior and attitude towards me. She treated me like dirt and to say the least she doesn’t possess any customer service s****s to be a manager let alone the cashier. People like her don’t deserve to be working for such a big brand. I hope your CCTV footage will reveal how calm I was while I was receiving the worst service I have ever experienced and I hope something is done with this. My reference number 441548.
