Read kezardinjnr's link. There were people who bought Skyrim in Australia, but received the Asian version; it's not common as in 'happens all the time', but I've seen a few of these threads.

Contacting PS support is the best idea, yes.

yea but i rahter let my money go than tangle with sony thank u guys for your help

You could always try contacting support. Since there was only 1 dlc version available in the store means you're not at fault.

Sony support is actually really helpful. It's not tangling with them, just something happened.

This.
