Things like that are bound to happen. The only time I ever sent money out of state was when I paid Animenation for a whole shipment of stuff, and that went all right. I just got the PMOs and sent them direct... and no problems occurred along the way. You can't tell if someone's going to steal your money or not, because... well, there's a 50-50 chance of that happening.
I'm from Malaysia too, wish I could help but... I don't see any way in which I can. +__+
P/S: Cash or PMO?
