Marc Jacob Apple Tote

My cousin won a Marc Jacob Apple Tote from TheLuxyVogue Facebook - Weekly Giveaway on 30 April 2012, but until now she has not received it.
Even when she wrote to them via email and left a comment on their facebook, there's no reply.

She presumed that they have sent it out, so she emailed them again asking for a description of the package and date sent, wanting to lodge a lost mail complaint with SingPost.  There's no reply again.

I wonder why ???
If they really did send out the package to her unsuccessfully, it should have been returned to them already. 
Why are they not responding to her emails?
It's really disappointing and it's obvious that they have very poor attitude.

Guess, they didn't even send it out.
