well it is not to say inaccurate but rather slow in update. Do not rely on the poslaju website tracking as it nvr update and you couldn't trace anything too. Call to helpline and ask!

Usually within klg valley and the pick up time is around 3pm to 5pm. Meaning if u send in your parcel to pos office before this time and your goods able to send out within the same day and arrive the next day to the destination!

If you want to know the status of the goods it is advisable for u to call the helpling only the day after sent out. This is to be fair to both seller and buyer sides withinout creating funny issue.

In between, if we doubt of poslaju service and complaining around lost parcel inaccuracy no update in tracking details etcetcetc... so pay higher and go for DHL
