Full tracking of EMS Service, Argentina

I sent a gift for my friend via EMS service from Seoul, South Korea to Argentina.
I thought it took about a week. But it wasn't.
My friend said that the gift didn't arrive after a week.
Track and trace site is very popular site to trace the package.
But some countries case, full tracking is not available.

So I use local post's site, in Argentina, to full tracking.
