There are a couple of possibilities when you feel that you're not being understood. Of course, it could be the other person is being obtuse or even thick. The other possibility is that you are not expressing yourself as clearly as you think you are. Bearing in mind that the people whose help you're seeking are volunteers, giving of their time and knowledge for free to try and help you, do you think that this:

Is the best way to interact with them?
Just to demonstrate that yes, I was reading, let me reassure you that I stopped right there. Good luck with your issue.
