Order not delivered. No communication

I place an order online on Black Friday. I needed the order for an event on the 16th December. Today.... A month later, I have not received my order!!!! I can understand if there's a backlog of order due to Black Friday but why not communicate? My order has been "packed" since the 4th of December. I have been calling Makro, week in and week out, to find out what is happening with my order. The consultants always say they will return to me and they never do! Not to mention how I now had to stand guard my entire December and always make sure that I'm home incase they deliver on that day!! What a nightmare!!!! This service is despicable for such a retail giant!!!
