Wrong order

Good day

I visited Gateway branch today and i placed an order for 4 chicken wings and chips, plus a buddy coke. The lady who assisted me was half asleep, i had to wait 20min, then order came and she never check it and gave a can coke, i had to remind her i ordered a buddy bottle. When i got home, i saw that the lady who was sleeping, gave me slider burger and two wings, that definitely did not look anything like what i originally ordered, 4 wings and chips.

I would like to be compensated for it and please ensure your staff are alert and check orders.
