Makro bad service

I am really unhappy regarding my online order with Makro. On querying my order on Friday (9 Dec) morning, I was told that it was to be delivered by 5pm on the day. I also had to make a change for the delivery address as the street name was incorrect. The customer agent also said that the courier had already collected on Wednesday (7 Dec) according to what she saw on their system. At around 4:15pm, I called Makro again to see if there were any issues with the delivery. I was told that it is still marked on their system for delivery. I was also given the couriers number which I called and was told by them that they had only gone to collect on Friday (9 Dec) and that it was not ready for collection. They were not very helpful and quite frankly I thought quite rude. I then called Makro again and explained to the agent what I was told, and she said she would escalate it. I also asked that I please be contacted as to what the actual status was and when I will be receiving my order. If the courier had it or if it had not yet been collected as neither Makro nor the courier seem to actually know where my order is. Still waiting for any form of update. This is really shockingly poor customer service. I need to know what is happening with my order and would appreciate some form of feedback or a telephone call.
