I am informed that the 2 parcels haven't arrived to NSEC by yesterday and Sakai san asked me to find out their current status.
Japan Post informed me as following:
First parcel shipped on 16 Mar : EL021219825JP -> On delivering (19 Mar) Second parcel shipped on 17 Mar : EL021013013JP -> Reserved because of absence of receiver (19 Mar)
But Japan Post cannot reach further details of the status.
So, will you please ask Thai Post about their status?
