This would not be the first time GFK had an accounting error resulting in duplicate or over payment. I really don't understand how it could be a scam unless the email was requesting the money be sent to a different account. If it is the same as the time it happened to me, I just needed to reverse the payment through PayPal directly back to GFK.
