Bad quality

I am so livid I bought a pair of Asics shoes at Sportsmans Warehouse Rondebosh.Six months later the paint comes of the shoe.When I take the shoe back a million questions is asked as if I stole the shoe.I am a Nike fan and should have stayed with Nike as I think their quality of shoe would have been better.I paid R1600.00 for the shoe now i'm being told it's the customers fault.How can paint just sc**** of the shoe and I basically use it for Gym purposes.And the paint came of in the left side of the shoe.I'm not happy with Asics and sportsmans warehouse what a *******.
