Makro - worst customer service

I placed an order on 28 November with a 7-10 day delivery commitment. I have been phoning the Makro customer service line for a week and not once have they been able to tell me where my order is. I have been told that it is being packed at the distribution centre, now they are waiting for the courier to collect but no one can tell me when that will be. Not sure why Makro has a customer service line because they can help you with nothing. I asked where this warehouse is that my order is lying in and apparently they do not know. Really, you do not know where your own warehouse is???? I have been promised a call from a Supervisor and escalation unit about 4 times and not once have I been contacted. I have phoned, emailed and private messages on their Facebook page but nobody gets back to you. This is the most pathetic service especially for such a big retailer. I can safely say I will never buy from you online again and will warn everyone I know not to do the same.
