Product Quality and policy

I bought a microwave 37 days ago from Makro Alberton.<br> After 28 days the microwave stopped working. I brought it back to the store to replace but now the product needs to be sent to the supplier for verification . I would now be without a working microwave for longer than I owned the working microwave.<br> The store advised that the return policy is 14 days but this is not a return and would just like the product replaced. Even if the supplier finds fault I do not want the exact microwave as this unit is faulty.<br> I feel you need to address the policy regarding this.
