Waiting on refund!

I bought a Keter Manor Pent Shed from Makro Online over two weeks ago. When I opened the box almost all of the panels were damaged. It's a shocking quality. I immediately logged a return which said I would be contacted by a courier to arrange collection. I've followed up more than 4 times and each time I get told it's been escalated and nothing happens. I've since discovered they have been escalating to the supplier. I don't care what happens with the supplier. I bought this from Makro and I expect Makro to arrange collection and refund me. I got a call from the supplier yesterday asking me if I want replacement parts?! I don't know how else to communicate that I want a refund. I can't seem to get hold of a manager contact either. So frustrating. I will never order from Makro again. Horrible Customer experience.
