Pep Stores review: Poor customer service

I went to buy school uniform at pep store van wyk street in roodepoort. Service is very poor. No staff to help customers on the sales floor, we help ourselves and opened a lot of school shirts as we were looking for correct sizes and we're fitting on the floor.
I then took 6 wrapping paper priced r0,49 each. I noticed that it scans 6.99 and notified the cashier that it's r0, 49 she then told me it's a wrong price and she called manager by the name of tumi. He also told me that's not the correct price and he can only allow me to pay for one only. What a terrible service. What happened to the price you see is the price you pay?
Consumer rights does not exist in pep store van wyk street. I am very unhappy with their service.
