loose your bad attitude or business

Bought a second ps3 game from cash crusaders monday paid about R160(grand theft auto 4).Went home after my purchase and loaded the game.The game only halfway through.The next day I took the game back for a exchange. Power was out. They said I should come back when they have power. The following day went back again. The person I spoke to was not there. A sales rep took the game and asked me too choose a different game or something else.Unfortunately there was nothing I wanted because there was so little ps3 stock. They took the game to the back.asked me to following them.They loaded it on to a different ps3 and it loaded. I told them that it doesn't want to load on to my ps3. A sales rep was so disrespectful after that. By telling me am I done she has other customers to help. I asked her what should I do with a game I paid for but doesn't load. She responded by by asking me a series of questions.Does my ps3 have enough space.ect. I rep**** by yes to all the questions.Then she told me there is a problem with my ps3. I rep**** by that can't be cause I loaded another game the same day. she started getting work up and said it is my ps3 cause the game loads here.i left shock Disappointe
