Bad service delivery

WORST CUSTOMER SERVICE I bought a laptop cash from game in February at Game Beacon Bay East London. Used the laptop approximately 10 to 15 before the laptop stop working. Then took the laptop back to Game Beacon Bay East London where a gentleman in the electronics department took the laptop and said that they would take a look at it and get back to me. Well 3 weeks went by and then the gent from game contacted me to tell me that they only needed to reset the charging block and it was all in order and working again. I then collected the laptop and upon arriving at home I charged the laptop for approximately 3 hours. Then out it on and used I for approximately 1hr and boom laptop did exactly the same thing as before. I then called the gent that had dealt with my laptop issue the 1st time and told him that the laptop had done exactly the same thing as the first time. I also expressed that I was happy with the laptop and felt that I deserved a replacement laptop and not getting it fixed. He the gentleman also agreed that I should get replacement laptop and that he would have a chat with his manager and revert back to me within a hour. Well 24hrs had passed and to no avail has anyone contacted me about my laptop. I then tried calling game to ask to speak with a manager and got a also to no avail did I get to speak with a manager as the phone operator Mzi was very rude about me skating to speak with a manager. Bare in mind that the laptop is on 6 months old and has only been used approximately 10 to 15 times. Very disappointed in the way my complaint has been dealt with. R4000 cash is no joke..........
