Makro delivery fail

I purchased a tv online on 25 November 2019. According to Makro delivery terms and conditions, it should take about 2-5 working days. I then logged a query on the 2nd or 3rd of December, stating that I have not received my TV yet. I received a response on 6 December. The consultant told me that they had no tv's in stock at the Cape Gate brance but they will look if the other branches have stock. I also called numerous times, waiting long to speak to a consultant, but no one could help me. How does such a massive shop not keep track of the amount of products left in stock. Should the unavailability of the item not reflect on the online store system? This is ridiculous. It is 12 December, I still have no tv and no solution. I am very disappointed in the service of Makro. It was my first online shopping experience with their store. I am definitely not buying online with them again. Customer service is slow and your problems are not solved. They are not living uo to their policy, but yet they have my money.
