Customer buys computer. Customer opens computer. Customer screws computer. Customer comes to my store asking me to find the problem saying nothing about his actions. I spend 2 days over a dead PC with faulty HDD trying to figure it out, save his data and most of all trying to make sure everything works as it should. Ask him to pay at least for damaged MB which i cannot send to supplier for replacement as its obviously mechanically damaged. Refuses claims its my fault, it was like that when i build it for him and the HDD is "obviously used as it cannot be damaged in 1-2 months he has the computer".....Makes a scene, shouts, demands to get his computer back or he will go to the police etc... i give him his computer, say nothing but start secure label all computers, even not mine but those i serviced over the time.. I need to know what is going on with the computer that YOU made so i can fix it faster, easier and cheaper... for customer and me.. long story short, this guy was friend of a customer etc and few months later i hear about the story of this guy who opened he new PC removed the HDD, dropped it after having RAM removed, reinstalled, couldnt make it, forced it, damaged RAM Slot, managed to insert it the right way only to find the PC wouldnt boot anymore but didnt pay anything because "these small stores are afraid of the police or something and why "we must buy from big companies to be safe"
