Online Order not delivered and overdue

I have ordered an deep freezer online on 23rd November, and I have made numerous calls to the call centre with no progress, I get told that they will follow up with a courier for past two weeks. You can imagine getting same response with no feedback of when the courier will order. I have heard Makro delivery fast but this is disappointing. I ordered fridge with a colleague hers is delivered but I am not getting any joy. management please help out, Its frustrating to wait for an order for too long
