Makro has lost a loyal longstanding customer

I purchased a gas hob from Makro (online) and it turned out that it was too small. When I tried to return it Makro said it will not receive it back since it has passed the 14 day return period. The product has not been used and is in its original packaging. I was actually told to look up the marketplace supplier - Ferre - and see if they can help me. I have been told that they cannot assist me either. This is +R4k lost on top of having to buy another stove.
