Damaged goods-Dissatisfied client of Makro

Bought a fridge which was supposed to be new however only to find that it was 2nd hand and that was definitely not what I paid for. I sent an email to Makro today and didn't even receive an acknowledgement. I'm supper disappointed and annoyed by this level of service especially when they have my money upfront. I really need them to come get their damaged goods either bring me a new one or my money back as soon as possible.
