Attitude from employees at KFC drive-thru in Musina, Limpopo

I was ordering a certain meal at drive-thru and the lady (Ndivhuwo) kept on asking what do I want to order, in the background she kept talking to someone else. After realising she was trying to multitask I simple asked her to attend to whatever she was doing then she will get back to me when she’s done. She then refused to take my order and asked another lady to take my order. When I arrived at the paying window she didn’t even bother apologising she just said the amount I needed to pay. When I arrived at collection I explained to the lady there “Mahlatse” who by the voice I remember it’s the 2nd lady that took my order. I explained that I wasn’t happy with the service and attitude I am receiving, she just said you can complain using the slip, what happened to “we apologise for the inconvenience”. Some people must just resign if they don’t need job because there’s a lot of people that need this job and can do even better on it. KFC is a big brand and it pains to see such employees downgrading the quality of this brand by being humanly rude and insulting. Please teach your employees customer service.
