No assistance makro

I went to Makro riversands to purchase an action camera, when I got there I waited for just over 10 minutes for someone to assist which never happened so I went looking for someone. The next person I asked for assistance said they were coming now and I waited for almost another 10 minutes till I went looking for a manager and was told the manager is in a meeting. I asked this person for assistance who called someone else. I chose the camera I wanted and waited for almost another 10 minutes only to be told there's no stock so I ask for a manager again and 1 comes to assist. She needs to learn how to be a manager and manage situations, she said if I want the item I should go to crown mines, that's on the other end of jhb from where I work or live yet she said she provided me with a solution. She doesn't listen, was sarcastic and condescending and expected me know that DC on the price tag means discontinued. How should I know that? I don't work at Makro. She then insisted that I ask for her name instead of use the name on her name tag. Poor management, no problem solving ability, unable to communicate effectively and not willing to go leave alone the extra mile but any mile for the customer and tried to argue with me to the point I asked her to leave me alone because I don't want to argue. If I wasn't in need of this item, I wouldn't have purchased it from that store and we shop there almost every week. She said they don't have stock so I questioned why is it still advertised on the shelf and she said they only have display units and they can't take out the sign till they sell those and she offered to sell it to me. They brought units in boxes and not the units on display so where did the stock come from? It took almost 1 hour to purchase an item that should have taken 5 minutes. Then at the till a sales person put his sticker on the item yet he didn't even assist or answer 1 question about the product.
