k.wong, I totally feel your pain...
Case in point:
Have a EMS package from F2F that's been on the way to me for about 5 weeks now, and lo and behold - I contact them asking them why has it been in customs for 3 weeks now, they go off, investigating, then yesterday they call me and say that they can't find the package over here. Yes, you've lost a piece of Soundwave - with a chance of finding him... Aus Post on the other hand has lost... a whole package. Sh!t!
Happy belated birthday, btw!
But yeah- keep looking around - like behind the table etc - UNDER the printer ... cause it'll turn up! (don't throw away the packaging of the printer!)
