Dave may have scammed me

Dave had contacted me on his own skype, asking about my $20 I tunes giftcard. I complied, and sent him the correct code (was not already used before i sent, I scracted it the money he told me to send). He then proceeded to tell me the code didnt work. I told him to send me a picture of his balance, and after much arguing, he did. Here is the pic:

Now, I went to my Itunes, and you can see quite a difference in the font & placement of the numbers and "$" symbol.

Please help, I just wanted my fair share lol.
