Unhappy

I went to rage shoes& clothing at station square Pretoria today in the afternoon to buy pair of shoes which were on sale at R170.00 each and when I was at till paying the lady told me that the other pair of shoes is R235.00 so I have to add R65.00 then I told her that it's not my fault that they didn't remove the sale price and I want the shoes on amount of sale. They ended up telling me that that can't give it me coz they have to add out of their pockets and they don't have R65 until they called someone who told them that they must give me the shoes with the sale amount and they will deduct from their salaries. I'm not happy coz they've wasted my time while I waited there telling me that someone forgot to remove the prices and they were not that friendly while it wasn't my fault
