Personally, I think a lot of such rating system are baised in a negative manner. The reasons include:
1) People usually call customer service for a greivence, and they are in a "bad mood" already.
2) Negative ads attract attention more than positive one (something I REALLY hate).
Best thing is to judge a company service by your own experience. My experience with SE customer service is limited, but it went ok... Much better than my experience with Ver***n, but I usually only call them if my phone is not working -_- and I am in bad mood already. D*ll customer service is the only one I can remain quite "anger-free" when my laptop needs a fixing -_-

Art for the sake of truth, for the sake of what is
beautiful and good — that is the creed I seek.
