Ridiculous Warranty Service.

I have been waiting for a week for a response on Pinnacle breaking my laptop screen after taking it in for repair. How can one trust a place which promises to do repairs, and warranty services under the laptop manufacturer's warranty and actually do more damage? It is ridiculous, and there seems to be no signs of urgency from their side, even after explaining that I need the laptop to do my job and continue my education. Absolutely frustrating.
