The study in english is four years old, nothing newer? But then again, I don't live in England, Canada, or France, but I do know the three countries you listed all have services centres run directly by Apple. Other parts of Europe don't, and are serviced very differently.
It must be great living in a world where everyone is at your beck and call. The fact is, surveys from around the world showing that Apple has top notch customer service are all over the place, and surveys showing the opposite are hard if not impossible to find. Since it's clear that YOU are the center of the universe, we all know that no survey that doesn't include YOU and only YOU responding will never satisfy you, since you will always claim that the survey doesn't cover the Apple that YOU know. We know. It's all about you. You had terrible service from Apple. It happens. Bad luck.
I imagine it probably had something to do with you being a jerk to the customer service people, but that's just from watching you be a jerk to everyone here who has tried to answer your demanding questions only to be slapped in the face as a thank you.
I know one thing you've made everyone here assume....
