Sold me a defective Unit!!

told me the unit has no defects, but when i got home the unit's LCd keepsturning off by itself, and will come back after a minute. after a few more days the unit cant boot up anymore. i had it fixed nalang..

the unit;s not worth it, its all used up. prang lamog na.

my bet is he's buying these units from cellshops that sells them cheap, because of either thier repaired or not in tip-top condition.
