Bad Service Delivery

Today at around 20h42 we walked into the Long Road Welkom branch as they are playing loud music that we cannot speak to each other to buy food. As we were still looking at the menu deciding what we'll buy at 20h47 when a team member Maria rudely and unmannerly shouted at us from behind the counter "what do you want" in Sesotho. Not hearing her she shouted at the security guard to ask us what we want then afterwards closed the main door. Speaking amongst themselves to figure out what our order will be Kekeletso helped us again asking what the order is as they do not have enough pieces. In my mind I'm thinking that it is not yet 21h00 as business hours is until then. Even then they must made sure every customer has been helped. Whilst speaking to Kekeletso one other member was gossiping with the security and laughing while she passed us. Sipho, shift manager explained to us that there are not enough wings for our order. We immediately asked for a Manager's number cause clearly they do not know the NCPA regards section 54 They are basically required to deliver on their promises and to let their customers know if the service will not be delivered as agreed or promised,” They said that they cannot give us the number it is not allowed. After wasting a lot of our time Sipho again returned and told us that they are going to prepare a new batch. What has happened to excellent customer service and are we now dealing with securities rather than team members? Gossiping and joking about unhappy customers is plain rude and uncalled for. Playing loud music other than the KFC online radio is prohibited and then we have to shout to be heard. Closing earlier than normal business hours and showing customers away. We would like KFC to investigate this bad service delivery and rudeness.
