Not waiting 14 days for refund because of makro supplier

I ordered 7 items on Makro online and was unsatisfied with 2 items. One in particular the supplier sent me a gas stove that was different from the picture. It was a cheap stove I could have bought from the China's. I returned the item in order to get a refund.

My problem is it's not my fault your supplier sent me a cheap stove that was not advertised. So why must I now wait 14 days to get my money back. I bought the stove because of the picture and description but that's not what I received.

I don't want to wait 14 days for my money so please expedite my refund.
