Hi Hisashi, I'm answering this because my previous MNC French company used SkyNet.
First of all, Hisashi, it's a public holiday. Nobody will deliver stuff on a public holiday. :)
Secondly, you should have seen the amount of returned courier packages we got. If they cannot send to you the first time, They will not send it to you a second time. They will return to sender. End of story. It will cost us(sender) money to try and send to you a second time.
Sometimes, some couriers like UPS, they will toss the thing inside your house, if it was a couriered magazine or something like that. If they can't get a signature on the consignment note, they will return to sender.
POSlaju guys on the other hand will throw a note in your mailbox and say :First attempt at 1.15pm, 2nd Attempt at 1.45pm or something like that if they are still in the vicinity. The last line will read. Attempts to Deliver : Failed. Please collect from XXXX Post Office.
Thanks demonhunter, I appreciate much for your answer
I just saw the updated status, there will be a second attempt delivery. Like you said today Thaipusam off, plus Sunday off. Then I need to wait until Monday already.
