Completely ignored and no communication

On Sat on my way to visit friends I decide to get KFC as I hadnt eaten the whole day.We stop at KFC airport Mall (Belhar) and there is a long queue.Understandably the product is usually good and to be expected. I notice that the system in place is ridiculous as only 2 cashiers are available and they responsible for packing the orders and serving clients. I wait patiently until served.I order a boxit meal wanting a zinger burger with white mayo regular chips and 4 zinger wings. The cahier namely Talent takes the order and says nothing further. I am waiting about 10mins and ask her why am I still waiting for my food. She dosnt realise and checks my order again and asks where are the wings - they confirm from the back there is a waiting time of 4:30 mins.Another 10mins.I ask why she not advise me when placing the order that there is a waiting time to give me the client the right to decide.She responds with they didnt tell me!So here i am still waiting I ask but the wings came out why am I still waiting -Oh we dont have zinger burgers there is a waiting time for that also another 20mins -this after being in the shop for an hr. I ask to be refunded the manager Chantel offers no empathy
