Unreliable Online Shopping Experience

An online order #MAK*** was placed on 01 March 2021. I had to call the customer care centre to follow up on my order as it was still "in progress" on 09 March 2021, only to be told that 1) the order has breached its SLA and 2) there is no stock.

This is the second time ordering this item and with both orders, I was told that there is no stock. I am furious for several reasons: 1. This item can only be ordered online and when I order it it is in stock. Remember that I will not be allowed to buy it if it is not in stock. I just checked the site and the item is in stock 2. Surely if an order breaches SLA, why is the customer not informed about this. 3. This is purchased as a gift (in advance) only to find out that the person will not receive it in time

Makro's online purchasing process is very unreliable and I am doubting Makro's trustworthiness or lack thereof.
