Studio 88 staff theft

My sister was ****** of a R500 t-shirt after lay-buying clothes for her kids at the south gate mall branch. When she went to collect the cashier briefly opened the bag suddenly came and just put the bag in the shop's branded plastic bag, took the money and said thank you, proceeded to call the next customer. Then when my sister got home, a R500 t-shirt was missing and when she went to the store the manager simply said there was nothing he can do and that there were no cameras in the store!!!
