So, when I don't know an answer to a question, I just let them know that it is a great question and I will always get back to the customer before the end of the day with an answer if possible, of course. If it does take a little bit longer, I just follow up with a phone call and just let the customer know that, hey, given the certain particulars of this question, I do need to do a deep dive to see what we can do and then shortly after I will be able to give a specific scenario or specific answer for their specific question.
