Makro Order not delivered, but Order Status says complete

I ordered two items on the Black 5 Day sale. Only one of the items was delivered. My invoice also showed that one item was only delivered. Makro Online has however closed my order saying its complete. They took my money, did not deliver and now say my order is complete?? How do they also close an order where they can clearly see it hasn't been delivered? Is a reconciliation of order to delivery not done??

I have been calling every 2 days for almost 2 weeks and nothing has still been done about my other item. I just get told that its been escalated... and that they do not know why only one of the two items were delivered. More than 2 weeks and still no feedback.
