Today is public holiday, so is Pos Laju operational today?

Bought an item at 28/11/17 morning, I calculated maybe get on 29 or 30 because it Pos Laju, but the seller choose to ship it Yesterday at 30.

The address on my office, and I'm not even go to my office next week. So shit la this seller.

Do not know what make the delay, better bought it oversea, because RM100 cheaper, I thought spent RM100 more will save my time, but got seller like this, aiyoo.

So anyone knew? ALready try to google and found no answer

Also already tried to call CS, but cannot reach because of Public Holiday.
