Pep stores Maitland disgusting service

I'm appalled by the attitude I received at pep in Maitland by staff I purchased a pair of choose for my son and the shoes was with all the other marked down shoes on the shelf it had a label on it that said R34.99 on it no other tagged I got to the till and the cashier Johnathan was so rude and the attitude he gave me I was shocked that people that work in retail customer service can speak people like that there was another customer there with the same issue he told her she took off the tag to get another price. He called his manager to change the price and they charged me the full price of the shoe even though it was on the marked down shelf I told him this shoe didn't say 89.99 and it was on the marked down shelf he aid to me that another customer must have put this price on there I told him that's not my problem he then said to me it's not there problem either and wouldn't change the price the way he spoke and body language says a different thing. This is unacceptable how can a customer print of a label put it on the shoe and not take the shoe how does that make sense... I've been at many pep stores but never experienced this kind of service it appears to be a regular thing as they spoke to all there customers like that one floor assistant told a customer in the same isle as me no you can't fit the shoes on if you don't have money a elderly man how can you speak to your customers like that this is bad
