Paradise double paid my neteller?? advice

[sledghammer]

A buddy of mine lost 400$ to party or neteller fing up his cashout. He tried for months to get the money back, emailing party, emailing neteller, with nothing but a run around at every turn. If they cashed out extra money to me, I would keep it in a second. Of course, this was party and not paradise, and i don't know how paradise would have reacted to the situation.
