Product NON-Delivery - Missing in action.

I ordered and payed for an item from Makro Online for delivery. The product showed in stock and I provided all the details. The payment was approved and acknowledged by Makro. Delivery was stated to be between 2-5 working days. Status updates were supposed to be provided along the way to ensure delivery. Now 5 days have elapsed and I still do not have my product. Nobody can tell me where my order is. The online chat is non-responsive, the telephone support cannot help me and email response is not telling me where or when I can expect the product I paid for. This is total unacceptable service and making rethink about dealing or purchasing anything from Makro in the future.
