Still no delivery from Makro

After writting a review on Hellopeter about Makro a week ago about an order that I paid for and still have not received... I was called by the courier company saying they were coming to collect juices from me to return them to the store. I explained over and over to Makro customer care that all I want are the plastics that i paid for. The guy who was supposed to deliver plastics came with juices.. I told him that the was a mistake because I didn't order juices and he turned back with them. So why is Makro now demanding that I return juices that I didn't even sign for before they can deliver plastics that I have paid for?
