Transferred from pillar to post - still no solution

I received a call from Vodacom last year Aug/Sept where the consultant sold me a Mecer Guru laptop deal. Received the laptop and all was working fine, however when we wanted to charge it for the 2nd time, its not switching on at all. I've contacted Vodacom Customer Care and no one seems to know where this laptop should be repaired (its still under warranty). I've been given various numbers to call and still havent had any resolve to who needs to repair this laptop. I was informed to contact Digital Planet, but the lady told me that they dont repair Mecer brands. Please can someone get back to me urgently with the right details regarding the repairs for this laptop.
