Angry customer

Im not happy with Makro in Silver Lakes. I saw 1L Oros on their app being on special for R70 for 2, 2L and when got to the store i was told they've made an error of which they didn't rectify it in the app, i ended up paying money that i did not budget for it.

Joseph Makhubela and Yvonne Manoko are the one who showed me a small piece paper that says they made a mistake. I hope this get resolved soon because im not happy. Thank you
