Poor cabling quality

The hinge in the upper left corner of the laptop pinched the poorly insulated cable leading from the motherboard to the screen. I enquired at Acer's Main offices in Midrand and received a very lackadaisical and unhelpful response, I wasted over 400 rand on travel fees to get there. I've been trying to have to laptop repaired since last year July and have had no success in any direction, contacting their repairs center only achieved in me getting redirected to a different company that deals with spare parts with no relation to Acer themselves. It seems that they are either unable or unwilling to assist me in this issue and I am in dire need of a functioning laptop for my studies, I have been patient with them but I have finally reached the vestiges of my tolerance. A succinct response to this matter will be greatly appreciated.
