Makro online No delivery made

I ordered x2 items from Makro online on the 31st of July that cost me over R5000, the delivery date was supposed to be today but according to the Makro app absolutely no progress other than accepting my payment was made from 5 days ago. The app hasn't worked before but at least I received an email on the progress of my order before. Now, I haven't gotten a single email from them after the email confirmation of payment was made. I have emailed, whatsapped, Facebook messaged and called them to only received an automated Facebook message to say it's been handed over to the relevant department, that was at 8am this morning and I've received no other messages from them. These items are for my business and I've ordered everything from Makro online for it this whole year without any issues before but after spending so much money with no service, no response, no updates and no delivery as of yet I don't want to buy another thing from them. Can I just have my items delivered or my money back! I'd honestly spend more from somewhere more reliable
