Clowns

Where do you guys find these techs? I book in a working laptop, with a faulty back light. no problem with the laptop. I get a quote to get screen replaced, and accepted. 2 days later I get a call to tell my my motherboard has blown. ***??? this is poor, **** poor to be exact. and I must add the laptop was used with the faulty screen by hooking up an external screen for the past 3 months. nothing wrong with the laptop. something wrong with the ***** techs!
