My parcel has reached in JAKARTA, SOEKARNO HATA ON 23, its 31 of July, the Govt. Post website Indonesia is saying after 7 days, "Konfirmasi / Confirmation by Customs, KTSH 19000" could understand why the parcel is still not delivered.
Unless it's a holiday time it shouldn't usually take that long (this is Indonesia so who knows they could just be taking it a bit slow). Have you called the shipping agent?
I rely on shipments in for some of my work and over the past 2 years we've found the customs to be pretty quick (1 or 2 days).
There is a telephone Customer Service line where you can address (no pun intended) your inquiries. And they explain to you the code used and where the package is (with EMS/Pos); the tel. number of HaloPos is 161.
