thieves

I went to Tygervalley Edward street on Saturday with 8 of my friends,it was my first time there i had my hat on...i was advised to leave my hat at the door with security guy/bouncer...an hour later we left and no one knew where the hat was.I know the policy and thats why i left the hat at the door,The lady that i gave my hat to was not there when we left.I was advised she left.I want my hat back,i stay in Bellville.
