Terrible service from Makro Online

I orderred a trampoline online and had it deliverred on the 1st of April 2025. When inspecting the item, I could clearly see that this was not new. There were scratches on the steel frame and the handle bar mounting was broken of off the main frame. I asked for the item to be returned and for a refund. According to my online profile, the item would have been picked up from my residence on the 4th of April. Well today is the 8th and no word from Makro!!! I send 2 mails with no response. I then phoned customer care and was told that 'it will be picked up sometime in the next week' . So Makro expects me to sit at home like I did for the last week in case they decide to rock up. In the mean time Makro has the money that I paid for a NEW ITEM (and then received a used defective one) and they are not refunding because the item has not been collected by them on the date agreed by Makro. Why should that be my problem? Most definitly the last time I deal with Makro.
