Appling service

One of the reasons I bought Dell is that the computer can be fixed on site. I has 2 laptops needing fairly minor repairs, paid for the parts and the technician came out (10 days later). The first one went fine but with the second the technician fried the charger by placing an antistatic unit on the live charger pin and blowing the charger, and sending sparks all over the kitchen table. Surprise. The charger didn't work after that and the brand new screen as giving problems that an hour on a call with an offs**** specialist could not fix. I have now been sent a quote and they are EXPECTING ME TO REPLACE THE STUFF THEY BROKE!!!!
