I think what they meant was that the Postman wasn't able to deliver to you because of their own problem, not because you weren't home (if it was because you weren't home, they would have asked whether you want to arrange for a second delivery which is FOC one btw)

If your parcel is at the Batu Caves branch, and you want to self-collect, then you HAVE to go to the Batu Caves branch, as they cannot send to another branch one (Btw, are you sure the Bander Sri Damansara branch is a Pos Laju Center? It's different from post office one ya)

I suggest getting the Batu Caves Pos Laju Center telephone number, call them to complain, and tell them to put your parcel on priority.
I had a similar incident before but with me as the sender. That time it was the Puchong branch, and when I called that branch directly I was told they were overwhelmed with parcels but would put the one I sent on priority. The next day my receiver got the parcel d.

Hmm, that's odd. It should be the same branch one lo. Ask your seller again whether your seller gave the correct tracking number or not, or check with Pos Laju whether that number belongs to your parcel or not.

My suggestion for now is call 1-300-300-300 (the main customer service line), find out from them where your parcel is, ask them for the direct number, then deal with the office directly. That way you can confirm which office your parcel is at. Call tmrw only, you call now also no one will pick up.
