My thoughts on this was that the hacker was a casino employee and he had intentionally made the extra payments to the OP, then requested the repayment and siphoned the repayments into his own account via the new withdrawal method.
exactly. ...I mean come on...a bit of coincidence that the hacker fell upon this situation ...how lucky of him...to have successfully hacked a casino account and secondly to have hacked an account that owes money to the casino...
all very strange ...
