Missing item

My husband bought clothes at Edgars Kollonade. When we got home and took out the clothes an item waa missing. The item was scanned and on the slip but not in the bag. I phones customer care to find out what to do and they said to go back to the store to check if it's on the floor. The store had already closed as its a Sunday. How do i get my item? I cannot go in store during the week. Surely there must be a better way.
