Complaint Chicken licken

Bought 2 meals(chicken licken boshoff street Pietermaritzburg),it was a collection got there food was not prepared had to wait,when I arrived at the office I noticed the drummets were way too small(i took pictures they were half the size of my pinkie finger( I took pictures),i took the slip and went back to the shop asked for the manager showed her the food,she said those are the sizes they are serving i asked her if the franchise is aware of this she said i must gladly report it,i would be helping her,she didnt me the food nor give the chance for a refund. She doesn't seem trained in redress, dealing with customers nor complaints.I feel she should go for training to be better equipped to serve the public
