Not honouring product warranty

I bought a kettle in September 2014 which carries a 12 month warranty been experiencing an intermittent problem where the kettle does not automatically switch off when boiling. I took the kettle to Game in Queenstown where I explained my problem. They tested the kettle and it happened to work correctly at the time and the did not want to send it for repairs as it was an imported product and could not exchange it as it was \working". <br> <br> I again explained to them that the problem was intermittent and that the warranty clearly states that if the product is not performing as intended then the store must enforce the warranty.<br> <br> The fact that the kettle is imported is not my problem... I want the kettle fixed or replaced before the end of the warranty period."""
