Worst Online Shopping Experience - No help from Makro

Worst service I have ever received, just being ignored by Makro. I ordered two items together online for delivery. Only one item got delivered and my online order status says that the whole order is complete. I tried calling them and sent 3 emails and an online query to various staff members, with absolutely no response. I am still awaiting my other item that has been ordered and paid for. I don't even mind waiting longer for my item but the fact that NO ONE even feels the need to respond to my question (where is the product that I paid for), is beyond my comprehension!
