What is the Number you call if you lost your Walmart Associate Discount Card?

I seemed to have misplaced my walmart associate discount card and can not for the life of me find the number I call to report it missing and get a new one. If anyone happens to know the number can you please let me know. I really need to report it before it gets into the wrong persons hands.
