Bad customer service

I am not happy about what Edgars Secunda Mall did to me. A jacket was on the 50% rail, and the store manager plainly refuse to give me with the price I saw. My right as a consumer is to buy an item with the price I see being advertised. She was guessing that maybe a customer left it on that rail by mistake. And telling me that it is not her fault.what exactly does she mean, does she mean it's my fault?This Is not good customer service,I know what I saw, i am not making this up. And knowing my right as a consumer,i was made to look like a stupid when I know my rights.Edgars must do the right thing with their customers. By abiding and treating their customers fairly.All I want is to get that jacket with the price advertised
