Horrible service

Good day, I bought an iron at one of your stores, on the 26/08/2025. We used the iron with no issues, until quite recently, my wife decided to put some water in it, as we have never poured water in it before. Upon doing so, the iron started to leak, at the base, even when ironing, it would leak so much that it would wet whatever it is that you were ironing. I took it to a click store for an exchange, asking them to give me one that does not leak. It was taken to the back, 15 minutes later, the two Clicks employees emerged telling me there was nothing wrong with the iron, and granted, it was not leaking. When I got home, and my wife tried using it, it started leaking again, when I went back to the store, I was told that we were most likely using it wrong, which I found very insulting, as a 41 year old man, I have been using irons for a very long time, so for the Clicks personnel to assume that I can not use one. To which I proceeded to ask myself if maybe it was because I am black, and they assume that I live in a shack and have no formal education, therefore can not use Clicks' fancy irons, which it is not that fancy by the way, was again insulting. This happened at the Promenade store in Mitchells Plein, I would like this rectified, I have my purchase slip, which will be my last purchase at your store, all I ask for is an iron that will not leak whilst using it.
