Worst experience at Levi’s Menlyn

I went to Levi’s Menlyn store today on the 29th of January worse part on my birthday. There is a Jean I wanted to purchase, when I was ready to pay I noticed that the price put on the swiping machine is not the initial price that was priced on the Jean and I asked Jack Mangwangwayi who was assisting me. What he told me is that there must have been a printing error, I told him that can not be fault, the store should account for their mistakes and let me pay for the price displayed. He then mentioned that the manager(Christina Ndlovu) was not in the store and he couldn’t assist me I would have to come back some other time to get assisted with the matter. I did mention on several occasions that I had to travel all the way cause I don’t even stay around. He said there is nothing that he can do. And dismissed us. My question was how can A store run without a manager or a supervision who steps in when the other is not around or we all get dismissed when we have such incidences. I am not happy at all
