Wrong pricing

Pick n pay liquor Brooklyn... supervisor or manager doesn’t know what he is doing. The pricing on the alcohol I wanted was priced R71.99 on the certain ones. So I tell him that the price I see is what am gonna pay and that went on we argued about that he is busy telling the cashier on how to do things but he never asked the cashier on what was going on. Now we go forth and on explaining things now he charged me R72.55. Please explain to that guy that it’s not our fault that people who work with pricing things priced things wronged he must not come and explain to us to purchase whatever it is with the original price when it’s priced wronged
