Makro bad service

Ordered a fridge / freezer combo online from Makro to be delivered by 1 December as I was moving on 1 December. On 1 December they delivered the wrong product to the wrong address. It was clear that I wasn't going to get my delivery in time for my move so I canceled the order and requested a refund. I have been waiting 10 days with no answer only a lot of empty promises.
