refund or replace

on Saturday 13th purchased 2 games from the Tyger valley Store when I got home only the 1 game worked ,Took it back the Monday 15th and the young man in store checked and it worked informing me that I have to update the machine and it should solve my problem (did the update and guess what game is still not working ) .Went back this Morning as the slip said I have 10 days if there's a problem and was told by the manager to bring my Ps3 in so they can have a look at it ,and because the company cant refund me . I was very unhappy as this is now the 2nd time I have to come back <br> and all I wanted was a game that works ,I then told the manager to keep the game as he is refusing to refund my money back .I then called the head office and logged my complaint awaiting a call from Steven Moore note awaiting .....<br> I feel sad that my son spent his pocket money on a game that does`not work R299 and BT Game refuse to exchange ,replace or refund him
