Yes it is pretty obvious when the customer support person does not really have a clue what you are talking about, and clears the ticket by just guessing at which pre-canned answer from a list that seems to vaguely answer the question they wanted you to ask (and which I had already researched and read, hence my question) instead of giving you the answer the the question you actually asked, in specific detail. So either give them more useful answers to choose from, train them better, or let them send it to the "I have no idea how to answer this question" pile. Frustrating.
