I got a email about that I got 3 dollars but nothing in the balance

I just checked my email and 10 minutes ago I got an email that told me that I got 3 dollars for my first parchase but when I check gameflip nothing is showing up
edit: My friend got the same email but he actually got the 3 dollars
