Sleazy salesmen that will fleece honest people

Concerning Kase Artist at Cresta Mall in Johannesburg. (This should be a zero star rating.) I have been trying to find a tablet cover for my Huawei MatePad SE 11-inch tablet, there were none that fit at Incredible Connection and the staff there recommended going to the Huawei shop. Huawei does not make or sell covers at their shop and they recommended going to the Kase Artist shop. The salesman there was very pushy, demanding to see our phones, when he knew we were only there for a tablet cover. He pulled a tablet cover out of a cupboard and said he sold one recently but that they do not perfectly fit the Huawei tablets. It fitted ok enough to use while I try find a more fitting cover, so we agreed to get it. The cover is of poor quality and has no defining make or model, just a very cheap product that will do the job for a bit. I expected it would cost no more than R200, as proper covers cost around R550 at Incredible Connection. The salesman loaded the speedpoint and asked me to tap, I stupidly did not think to ask how much the cover costs and tapped, then entered my pin. When I saw the amount it was for R1200!!!! R1200 for a piece of **** cover, when the tablet itself only costs R3000. I have never experienced such a dishonest shop before and felt like this is all my fault. Upon checking out Google reviews I saw that it has happened to other people too at the Cresta Kase Artist store. So they are a dishonest bunch of sleazy salesmen and I am spreading the word. Do not support them.
