I BOUGHT A LAPTOP FOR MY SON IN JANUARY FOR R8000 IN MARCH THE LAPTOP JUST SHUT DOWN THEN I INFORMED INCREDIBLE SOLUTION THEY SUGGESTED THAT I BRING IT BACK BUT I COUDN'T BECAUSE MY SON STUDIES IN CAPE TOWN SO WHEN HE CAME BACK FOR JUNE HOLIDAYS WE TOOK THE LAPTOP BACK THEY TELLING ME THAT IT IS LIQUID DAMAGED AND THE WARRANTY DOES NOT COVER FOR THAT MY SON NEVER PUT ANY LIQUID ON THE LAPTOP. THEY QOUTED ME FOR R23000 AND I BOUGHT THE COMPUTER FOR R8000 I REALLY ANGRY AT THIS ******* MY SON DOES NOT HAVE ANY LAPTOP AND HE IS A UNIVERSITY STUDENT. TO MAKE THE MATTERS WORSE I USED MY CREDIT CARD TO BUY THIS LAPTOP ON A BUDGET INSTALLMENT OF 12 MONTHS. I'M PAYING FOR SOMETHING THAT I'M NOT USING. WHAT A *******
