I would have to punch my card in favor of the "Incompetent" party.
I also work in the customer service industry by co-managing a small family-run computer-repair/new system etc etc business, been in the area for going on 23 years strong now.
We have had an ever-increasing number of customers come in with their systems complaining on Geek Squad's ineptitude and their poor handling of mistakes or customer complaints.
And at the Best Buy closest to me, I personally know one of their "geeks" from high school
and DeVry University(dropout). No offense to him, but ahem, he don't know squat.
(We've also had a system or two come in almost straight from Best Buy and when we popped the cd's, lo and behold, what do we have here but certain OS install disks.
