Indeed on that last.
We all know that PW does not give refunds. There is never any point in asking for refunds from PW because they never give money back to you. There are things that PW can do to resolve issues but refunding RPs is not one of them. That is why people use an intermediate 'wallet' service like paypal that protects purchases with a dispute policy. Depending on the circumstances paypal will either award or deny a dispute depending on circumstances from both parties (the time period to rais a dispute is 45 days not 1 month - i checked it before making my post earlier). But that dispute process only happens if the problem cannot be resolved directly between the customer and the vendor. In the case at hand - between Dekon and PlayWith. And that is where that goodwill thing comes to play.
PlayWith is within their rights to award or decline resolution of this issue. Dekon is within his rights to request arbitration in the case of denial by PW. After all he spend a lot of real cash making the stuff he lost. To see the thief running around bragging about it only inflames the issue.
The ball is in PlayWith Interactive's court to deal with it. I hope they resolve it to everyone (except Luffy's) satisfaction.
The right way to handle this is to return Dekon's stolen virtual goods and block the person who stole them since there are records that it was done maliciously (server chat logs are available for perusal).
