Never ordering from Makro online

Good day, I have the most unprofessional experience with Makro online, on the 27th of October I made an order with Makro and I used my address as stipulated under location which essentially gives you the stock available near to you. I made my order only to see a wrong address showing .I called in first thing in the morning yesterday and was advised that it can be changed as it’s still on processing, this is the same thing I read under your website that delivery address can be changed provided that the order is on placed and not dispatched. I then got a notification that my order is handed over to courier and the old wrong address was still showing. I then called in again and I was still advised to relax it’s sorted out. I have an email from today at 12:30pm, saying that my address is amended and it’s sorted. To my surprise at 1pm the courier called saying he is at the address which was wrong. I am livid!!! I want my order and I don’t want any refund or cancellation. I want this fixed because I was reassured and **** too.
