Bad service at KFC Oliefantsfontein - Consumer Complaint for Kfc

Lerato the cashier was very rude, she went to the extent of going to the back and gossiping about us, and one by one the staff members came to see us, when it was us to get the food, she went to the back and said she wants to prepare a special order, we complained to KFC South Africa and requested the footage for the special order she insisted on preparing, but KFC only sent us an acknowledgement, no footage, if KFC is making special orders then why are we eating their food, we are supposed to trust them so to have confidence in them again we need to see what Lerato was doing at the back on the 13th of June 2018 after 19:00. This is the second time I am complaining as I am not satisfied with the reply, I would not advice anyone to go tho that KFC.
