Got order wrong x3 and got only half of order

So here you are opening a new branch and everyone is excited. I decided to take my whole family 7 people to enjoy some Chicken Licken..... To my disappointment the order was wrong. I understand that I had to wait for some of the items ordered as you sometimes do. We waited for LONG !!! Then when the girl came with the bags of food - I immediately saw that not everything is in the bag - (number of boxes right?) - So I quickly checked hoping that they would put the same type in 1 bag i.e. all the burgers in one bag etc. <br> NO THEY DID NOT !! I had to send her back three times as she kept coming back with either the wrong stuff or too little. Her excuse was there is a newbie in training and it is his fault ! NO it does not work that way. If you are training someone you stay with them to ensure they do what they should ! We ordered 6 burger meals, chicken wings and sliders. When I got home - we only got FOUR BURGERS !!!!! They did give us 6 extra wings, whoopdeedoo. I wanted to complain on Friday when it happened but no number on the slip !!! I paid a lot of money for what I did not receive. SO DISAPPOINTED !!!! How do you propose we fix this ???? I await your response New Quay Road !
