Bad service

Had the worst experience with Makro online. Purchased goods on the 24 January 2022. Only half of the order was delivered as tge rest was not in stock. Now in May 2022 received a call that they now had stock of which they can deliver in 2 days. I waited almost another 2 weeks. Called the call centre and everyday there is a new story. I requested a complete cancellation of my order. Today the order was delivered (which i cancelled ). Driver claims that he could not get hold of me. Which is a lie - as I am working from home. I refused taking the order as I have cancelled it 3 weeks ago. I need a refund and has been struggling to get it back..... I will never ever make use of Makro again. I need my refund
