Bad Customer Service/guarantee not applicable

I've bought two black office stools on 03 June 2015. Both of their seats broke and when I try and to bring it back and returned it, they called the ADMIN Manager to look at it. He decided not to change it, because accordindlt to him there were physical Damage. How can he just make that decision? I'm willing to sent the chair to an independent company, like CSIR, on my cost to proof him wrong!! He is giving Game a bad reputation! This is contradicting the CPA.<br> <br> Games Guarantees policy sucks!!
