Dang dude/dudess/dudette, sounds like you've been shafted!
I hope you don't think that all NZ citizens are as unscrupulous. Sounds like this one is the apple that makes the barrel rotten in your eyes though, and on behalf of my great country, I apologise.
Try "rotten egging" the office and letting them know it was you!
Hope whatever you do next works out for you,
Peace y'all,
