Free $20 Sephora giftcard

so I just now found out that on december 3rd Sephora mailed out giftcards for 20-15 dollars for people who are a part of their "beauty insiders" rewards program..WTF? I never got mine! there seems to be alot of controversy about this seeing as to some people never got it etc. check out the article where I found out or go to sephora's facebook wall. http://nouveaucheap.blogspot.com/2010/12/important-sephora-update.html
