Where is my order?!

Such disappointing service! A delivery was due 29 December. I requested for the address to be changed my order was not out for delivery as yet. I was told for the last 2 days my order has been escalated and I will.be provided feedback once they received feedback from the courier company. How can the courier company take 2 days to provide an update on the order? This is either Zando's way of blaming the courier company or their lack of management with an escalation.
