Anyone from Kuching/Samarahan (Sarawak) bought recently?

I had mine set for delivery to my office located in Samarahan (postcode = 94300).

Hasn't arrived for more than one month and as others have said it's untrackable.

Was told to try the local post office (is it POS Malaysia in this context?).

But there are so many...

Which one do I try my luck?
