One of my remaining two parcels just moved, so I hope by next week it will arrived in Thailand safe and sound, without any problem, especially custom clearance problem.
So there is a little light of hope that the reason why last parcel is still not process, is because 4HM just hold the parcel and add my custom service request stuffs inside that parcels to save their budget on sending separate box, containing only some of the missing pieces from previous order along with some of the replacement pieces for the previous error figures I received.
