Please try not to use weasel phrases like "Sorry you are having difficulty..." The poster clearly articulated the very real technical problems they are having with your broken unsubscribe process, doing your debugging work for you, and the phrasing of your response implies that the fault lies with the user. I don't think this was intentional weasel-speak on your part, but do please try to be aware of your audience.
