Dissatisfied customer

purchased two 29.90 mixed meal (Its the one with the free bag). Upon returning home to my utter disappointment it wasn't the correct meal. The zinger wings was missing from one of the bags. I called them immediately and was promised delivery in the next 40mins. Its been 5days later and I am still waiting. I believe it's the principle of the matter and to misinform customers should be taken very seriously. One very dissatisfied customer.
