Very bad service

This morning I went to KFC kollonade drive thru to order food,I asked the lady if the had wings?she yes we do have.After paying the other lady said we don't have wings wait for 45min,I said no why must i wait for so long they said there is wings.Another lady came to the window and just said take back your money if you can't wait.She just have me back my money.What kind of a service is that?I will never go there again,I still have my slip and I will not leave it like that,I want everybody to know what kind of service i got!
