Awful service KFC Croydon Wanzile is the worst manger ever

0 is waving would rate kfc Croydon. I went into the store a d ordered a zinger fully loaded box meal with a cup of cool drink. After paying she handed me a buddy and I saw the slip had buddy so i let it be, the manager had to come as the cashier Senate incorectly put in the order. I came home and found a normal burger and a piece of chicken! This is not the first time iver asked for a zinger and got normal. I called and spoke to the manger Wanzile and she said okay she will get the right order delivered by 19:30....at 19:50 I was starving and waiting for my incorrect order to be picked up and my right order to come through only to find out that apparantly the order was "correct" so no new food was on it's way!!!!not even a call to advise their assumption??? I have the slip where the food was voided and a pic of the wrong sauce...the service from KFC Croydon is disgusting and the manager should be fired as she definitely gave awful customer service.
