Still Not Receiving My Child Support

Almost a year ago I contacted the child support office gave them my ex-husbands name address and the name of the company he is working for. Still after all this time I have not heard back from them or received support. He however is making a very good living and has recently purchased a home for himself along with a dirt bike and other such nice things. What do I need to do to receive child support for our daughter? I thought a ss# surch would have been enough to verify the information and to have gotten the ball rolling.
