AIrcon trunking (shocked... for a while..)

Just went see my aircon trunking works earlier... to my horror they trunk in right in the middle of the wall!! Din even bother to hide it, or trunk it along the corner... Just what are they doing!! even my current 10 year aircon trunking know how make its look neater and nicer...
*SHOCKING*

Was complain to my dad on what harebrain aircon contractor I have hire when i saw this....

*opps*
