Qnet — Chairos Watch strap torn without even wearing it once.

I had taken the Chairos Grand PriX watch . And it was in the watch box itself and when opened to wear the same, it got torn into two parts with so much ease while wearing only.

How can brand new strap get rip up after I see the amount I have paid for the as said 'exclusive' watch.

I want a return, refund or / exchange asap.
