Item left behind at the store

Bought a couple of clothes there, and while packing the items for us, the very friendly cashier erroneously missed to pack one of the dresses. I only realised this oversight hours later when I got home. Called the store, spoke to a lady called Mapule who took my details and the details of the dress as it appears on my receipt and promised to investigate. An hour later I called them back and was promptly told the dress was at the store and that the cashier had realised the oversight after i had left the store but kept the dress safe for me. This incident could have gone quite badly and I'm grateful to both the cashier (sorry to have forgotten his name) and Mapule for assisting me. Thanks
