Incomplete -Wrong Order

I went to KFC today being the 31 of August at 13:25 as per invoice, I ordered a Box it combo and requested that they add Dunked wings instead of plain zinger wings for an additional R5. My order only came with 4 zinger wings, 4 dunked wings and regular chips. I understand that this order is incomplete as one can not pay R59.90 for 8 wings and chips. I did not even check my order at the store as I assumed it is correct only when i got to te office and had no time to return the order. I am so unhappy with this as it reflects people who work without following requested orders by clients. My invoice number is 042 Purchased at 31 August 2015 Chk1042
