Builders Warehouse Strubens Valley has no humanity towards customers

Builders Warehouse Strubens Valley. This store is run by a bunch of ******! My parents took last two heaters from the racking with price marked on shelf for R1199 each, and when they went to the cashier, all of a sudden there is no price on the system and it took them ONE HOUR to come back to my parents with price of R1699. When my parents went on with them about the price marked on the shelf, they first say both heaters were wrongly placed and after another hour and the store manager finally came to say the price marked was wrong.....I have to say that this business/store has no humanity at all, my dad is 66 years old and my 63 years old, they let both of them stand at the cashier for two hours only to tell them they put wrong price on the shelf, not to mention we in the middle of a serious convid-19 situation. I heard so many bad things about Builders Warehouse and Makro in the past and how they not doing well, obviously there is reason behind every business not doing well, and in this case we cal clearly see that THEY DO NOT CARE! They getting more like those badly run SOEs, but I think a business should have some humanity at least and not treat elderly people like **** and let them suffer because of the store's mistake. DAMN ON YOU BUILDERS WAREHOUSE. We all have parents and we all grow old one day, what you guys have done to my parents today put shame on you all!
