No update on delivery! Did not receive item purchased!

I purchased/ordered a chest freezer more than a week ago and latest expected delivery date was supposed to be the 9th and the reason I'm doing this complaint is coz there hasn't even been an update on the app which is worrying. I called them and they said the courier company would get hold of me but nobody got hold of me! This is so frustrating!!! I'm sorry but I will never ever order from Makro online again and I highly suggest that nobody orders from them! Makro please assist me with this
