Refund not given on product

I went into Kolonade store on 01 Sep and just by the door on display were Tevo Magneto Lantern. I switched on the demo on display and the light was amazing. I took one and proceeded with my shopping. On the 4th I went into Woodlands and picked another one. Later during the month I saw it at PNP and decided, because I get smart shopper points and Std bank points when purchasing, I bought the lanterns there as well and decided to bring bank the Game ones. When I get there I am told \Telemark"products only have a 14 day money back guarantee"
