Ebucks shop customer support rude and argumentative.

I logged a call for a return on a blender which I purchase 10 months ago, its a premium brand R1500 which has started rusting. I got a call from the consult today explaining they could not do a refund (they havent collected the item to assess it yet). I explain to the gentleman its a food grade product and they can return it to the supplier but I expect that the replacement needs to be stainless steel as stainless steel doesnt rust. If they cant do that then we have a bigger problem which needs to be documented and send to me. I will then take it up with whichever consumer council. He proceeded to get argumentative explaining that I had purchased from the ebucks store and that the laws of South Africa dont apply to the sale. That the terms and conditions of ebucks means they dont need to honor anything. I asked to speak to his manager or supervisor a few times during the call he ignored me before hanging up on me. Maybe Vitality, Greenbacks, Ucount, Absa Rewards would be a better option for me.
