Makro - still waiting on my delivery; poor service ONLINE and INSTORE!

I bought a desk online on 28/01/2019 from Makro. Their delivery time is 2-5 days. On 04/02/2019 I phoned to find out when I can expect the delivery. The consultant on the phone informed me that they had no stock... So I paid for a desk after checking online if there were stock available, which there were and then they tell there is no stock. I asked him why they didn't let me know that there will be a delay and he couldn't answer me. I asked him to please contact me again via email or phone call to keep me updated. Since then I have heard nothing. I have no idea if when and if I will get my desk. As a business owner this is a very urgent matter and if I knew that this was how they do business and deliveries I would have chosen a different shop to buy from as I cannot do my work without a desk. Two weeks before ordering this desk online, I spent a whole morning at the Centurion branch trying to buy a desk, waited very long to find out there is no stock in store. The lady helping me took my number and said she will contact me to let me know when they can help me. Therefore after waiting two weeks I decided to shop online where there were stock available. In total this has taken 3 weeks going for a month. I would love some feedback regarding the delivery of the desk I so urgently need. This is disappointing and I am not at all impressed with the way Makro conducts their business!! Very poor service!!
