Who do I contact with a question about the ESTA?

My nationality makes me eligible for the ESTA and I have applied for the ESTA successfully 2 years ago.
However, I am not sure how to answer one of the new questions in the ESTA questionnaire (added somewhere in 2016 I think). Who can I consult about this?
I have tried the U.S. consulate in Amsterdam, but their phone computer states explicitly that they cannot provide support on answering any questions concerning the ESTA. I got hold of a USA visa support desk, but they could only redirect me to the general US travel website and also were not allowed to answer my question.
