Well I received the quite generic reply below:
"Dear XXXXXX,
These days HK post site has a small problem.
They are working hard to resolve it.
This means the problem is just the tracking number could not work, but your parcel is in the transit.
Don't worry about this.
It will work soon.
Please be a little patient.
Have a nice day.

Strange thing is that the problem affects the ones who had their item supposedly shipped on the 28th, but the ones shipped on 27th not.
Oh dear, what have I done...
