Failure to Fulfill Guarantee

On the 12/12/14 I bought a WAHL Kit at Game Store Jabulani Mall which came with a 1year guarantee.The device began to give me problems in 02/15.I returned it on the 02/03/2015 to Game & they booked it in for repairs.I received a call from Game 2weeks later informing me that I need to pay R275.00 for them to repair the device.I asked them why I should pay for something that is still under guarantee,which I bought for so much & did not even last for 2months.I went back to the store & spoke to Patrick Ntanzi,I explained to him my situation,he mentioned that 2customers went to the store previous day to complain about the same problem & he told me there's nothing they can do if I can't pay that amount as is my responsibility as a customer to make the payment if I want my device to be fixed,I asked him if he's aware of the guarantee terms,he told me that he is fully aware & explained that the guarantee doesn't cover the whole device it only covers the motor.I asked him where is it written because it was the first time I heard about it,nobody explained when I bought the device,I left the device at the store.What annoys me is that Patrick didn't apologise that it might be a factory fault
