Lazy manager and pricing *******s

I wanted a bento lunch box 1.25 l Sistema . I got there they had pricing for a product lower (1.2l - R99 nd 2 l(R179)lunch boxes). To my surprice at the till Patricia the cashier tells me its R220. I told her thats not possible based on the pricing, we went to the shelf she saw THE LACK OFF PRICES ,then she proceeded to talk to manager . The manager said he will stick to that price or if i give praticia some problems he wlll come to DEAL WITH ME . THE **** IS THAT!!! THAT MANEGER BARELY WENT TO THE SHELF AND CHECK THE LACK OF PRICING FOR MY PRODUCT. the audacity to talk a till away from me like i wont hear nothing. Im DISGUSTED by this so called manager of yours .I HAVE NEVER SEEN SUCH PATHETIC SERVICE AND LAZINESS
