Designing Walk In Closet -Wire Shelving System, not so great

I thought the wire shelving system was a good idea for a small walk in closet, but unfortunately when I began to hang the clothes one of the shelves dislodged from the bar designed to hold it up..., or really more out -it seems to be designed to work under tension. I tied them down with picture hanging wire for now, but will replace them with something rock solid. I also concluded that I want the clothes to hang higher and then install drawers underneath.
