Double priced and rudest Costomer service

I went to the cash converters yesterday and saw a X-box 360 game called bully that I wanted to purchase, on looking at the price I see 2 prices R69 and then R99, so with the game in hand I approached the guy behind the till wen he saw the R69 price he aggressively started pulling the sticker off as fast as possible immediately as far as I am aware consumerism right says if a product contains 2 prices you have the right to pay the lesser one, but this rude dude at the back of the till wash not willing to negotiate and we had to pay R99 so I just left the game right there, I find it highly ********* business practices to treat your costomer right n such a manner with such a unhelpful attitude never seeing me again can’t believe that they call that service and then the employee treats me like **** really not on...
