Bad service & Disrespectful attendant

On Friday the 4th November we visited KFC at Lukhanji Mall in Queenstown (Eastern Cape) we were a group of church ladies. The service we got from staff member by the name of Asanda was very bad. Firstly two of us went to queue by the till, the driver and one lady for more than 10 minutes with no one available by all tills. While they two queued the others went to place their order on the kiosk, when the driver was finally assisted by Asanda her way of talking to the man was very inappropriate when he ordered with insufficient cash instead of advising the man it won't be sufficient cash she asked if the driver thinks it's enough cash for his order. Nevertheless we ordered by the kiosk then when we got to collect our orders some of us did not receive their collecting sms. We got to the very same Asanda whereby she said how we think she'll be able to give us orders without sms we explained that maybe to network issues there's a delay in the sms she demanded that those with no sms to stand aside fair enough they waited aside. She got to myself luckily I took a snapshot of my order number and gave it to her she then prepared my order, to find out my other was wrong so I returned it to Asanda and told her it's wrong and short too. She told me it's not her fault I ordered at the kiosk and they have no Coke she can only give Coke no sugar when I asked if she can refund me for the cooldrink she asked how because I ordered by the kiosk. In the end I was refunded and my incorrect order fixed. We asked Asanda if there's no way that she can check for those with no sms since her system was not working to show her queued orders for collection she then said how will she know if what we say we ordered at the kiosk is correct and that we shouldn't have ordered by the kiosk in the first place. It was almost an hour while we were at KFC for service while there were two other gentleman behind us in the queue that were waiting for service so when the other customer asked if he can't be serviced meanwhile Asanda is trying to sort us out she rep**** back that the customer should learn to be patient. We wanted to buy ice cream too but Asanda's response was that she doesn't know if there is since she hasn't sold any ice cream so in that case we ended up not asking for the ice cream purchase. What was even more frustrating is that before we went to KFC Lukhanji Mall we stopped at KFC pick n pay drive thru and also waited there for 45 minutes without any service to the vehicles but they were busy helping walking customers that went in front of the cars to order. It is whereby we ended up going to the one at Lukhanji Mall and we also spended there almost an hour with bad, disrespectful, poor and dragging service given by Asanda
