What is the correct procedure for dealing with Credit "disputes" and chargebacks?
From time to time I receive emails from Facebook indicating that a user has "disputed" a purchase made using credits - usually saying that they didn't get their in-game points.  9 times out of 10 when I investigate, I find that not only have they received their points, but they've gone ahead and spent them on items in the game.  I keep very detailed records so I can be certain of this.  My question is this - exactly what are we supposed to be doing in situations like this?  I feel like I am being scammed by some of these people who are just taking advantage of the ability to dispute things.  Is there something I am supposed to implement in my credits callback to prevent this kind of thing from happening?  

Thank you for your time - if there is a better place for a question like this, please let me know.  I looked around and have had such a difficult time trying to find any place to get any kind of support at all with Facebook credits.
