USPS and UPS is the same company?

easiest way is to contact customs and check whats the status and where is your package.

for fastest clearance, go yourself to KLIA to get it done.

maybe u can check with the USPS representitve for malaysia?
or just check their website if you have their tracking number.

in my opinion, i'd rather trust USPS. u know these damn malaysians cant do their work worth for nuts.
most probably your package is just behind the table and their just too lazy to get off their damn asses and walk down the table to get it.

i thought USPS uses normal pos malaysia tracking - posdaftar?
