Usually when they deliver something and we're not at home they'll leave this notice paper that can be use to get my item at the post office right?

But what if they didn't give me the notice paper, but I only have tracking number, can still get my item at the post office? When I track the number at the website it says, "Unsuccessful delivery" but I didn't receive any resit or anything, can just use the tracking number?

whaat really? how could they do that.
If let say I'm too busy to collect it, will they do a second delivery trip tomorrow to my place? or I have to inform them first?

ok thanks for the info guys

If 3rd time also unsuccessful they'll keep it at the pos office right? they won't send it back to the sender?

ok have to pick up by myself then, but this is the first time anything like this had happened to me, had receive stuff from pos laju quite a number of times already.
thanks for informing.
