Yikes, you chose a very bad time to ask this question. I will try to be fair and balanced in my opinion, although I cannot say there will be some personal flavor thrown into my statements.
SE is a very large company with many divisions and I even believe some separately owned companies which operate independently while working for SE. Being a North American customer I believe we are dealing with one of these separate entities, that although in essence owned by SE, is really just another company striving to succeed. My experience with the customer service available to NA clients can be described in one word, frustrating.
From automated responses to customer service reps that seem void of life, the feeling of communicating with another human being is all but absent. This would not be so much of a deal breaker if the information given would suffice, but rarely does it achieve this mark. When paying customers who have done no wrong are wrongfully banned, SE's response is that they cannot give you an answer. For a user who feels they have done no wrong, it is impossible to change their actions without being given something to change. Had your account hacked? Fill out a notarized form and wait for SEs approval, which is not guaranteed by the way.
That said, there are some positive aspects about SE's customer service that I appreciate. In my experience the response from SE has always been very prompt, making me wait less than 24 hours for most e-mail responses (if by phone less than 20 mins, if by chat less than 30 minutes). Although sometimes their rules are annoying and cumbersome, it is good they will not bend...every customer gets the same treatment, its just unfortunate the treatment isn't slightly better.
So in summary, SE has very little style in their customer service, but they understand the importance of a prompt reply and easy accessibility. SE fails in giving a quality reply that feels sincere, almost as if you are speaking to a robot.
Best of luck with your report!
