They took a perfectly good desktop system, swapped the working memory out with one that was broken and then called in ten on-site technicians to diagnose the problem.
Three of them got it right (a $25 repair) but one of them went so far as to say that the hard disk needed to be opened in a clean-room for the data extraction (they quoted about $2,000 for a $700 job) Most of them stated the the entire motherboard needed replacement (a couple hundred bucks).
Stunning lack of ethics or intelligence or both...
