Poor and unfriendly service

I went to Chicken Licken Boulders Mall in Midrand and the service was really bad. I got there on the 5.5.2022 time 17:40 PM got to the counter placed my order and the cashier lady told me that "there's a delay of 15minutes on orders am I willing to wait?" I said yes meaning I will be out before 18:00 PM to my surprise after 6PM I was still there waiting for the order with other customers and we started chit chatting about the time we've been waiting, we (customers) decided to go and ask what was happening, the two ladies at the counter unfriendly face just said the meat is still in the oven, then I said but you said I must wait 15minutes, that time has passed where is my order, she said wait 8 more minutes. We waited with other customers 8 Minutes passed 18:30 PM we were still waiting !8:40 two ladies (customers) said they want to cancel the order, then I asked the cashier to call the manager she ignored me, I had to request again for the manager, cashier just screamed the manager's name and continued to assist incoming customers. I even said "your manager is just like the chicken that is not coming out of the oven, please call your manager" the cashier went at the back to call the manager but before she left she said " Sengi la" meaning I am fed up. They eventually came out together and the chicken was also out we said our complaints to the manager and she only apologized even after telling her about the poor and unfriendly service received. They just need to improve how to communicate with customers and be friendly as well
