Poor online Makro services and unfair customer treatment.

I purchased bulk items online on the 4th of November for my business which had to be delivered to the client on the 8th in the morning, and it was indicated to me that the goods will be delivered by the 6th of November. Indeed I received an sms on the 5th that my items were dispatched and handed to the courier on the 5th of November, I then received an sms promising me that my goods will be delivered on the 6th in which that never happened. I called the shop which was carnival city and there gentlemen I spoke to on the 7th in the morning told me that their courier driver did not fetch the order and there was no reason why. He then promised to investigate and call me around 1pm during that day which never happened. I then called the National call centre to find out about the status of my order since I needed that order o the 8th in the morning and we had a conference call with the shop where they just said to me that they will try to find a driver for me in which that also never happened. I then called Makro carnival city again to on the 8th in the morning to cancel the order since I had to use my own money again to go buy those goods somewhere else and that was not done. I had sent an email to cancel the order during the day and no response was received. I then called again on Saturday the 9th of November to cancel the order and only then it was supposedly done but I still did not receive any confirmation of the cancellation. I had to call on the Monday only to be told that my funds will be reversed between to 5 to 15 working days . Till today this matter has still not been treated with the urgency it required. I had to wait for days to get my order until the deadline was not met and now I still have to wait for days to get my money back. This is really appalling and disappointing service. This is also unfair to me as a customer because it is not my fault that a big shop like Makro could not simply get driver to deliver an order on the promised date.
