Do shops still sabotage cars for profit?

Hate to hear about this kinda stuff.Seems they always try and pull that stuff with women who have no way to know whether or not to trust them.
I suspect with the economy the way it is this is way outta control . Unfortunately there's probably little to keep it in check .One used to be able to contact the bureau of automotive repair .And they would mediate for you .
And that would put the shop on notice that they would be watched .And possibly investigated.Like every other Service though it's probably been cut to the bone.
