How do you respond when you do not know the answer to the question? Fantastic. First thing I've always realized is that you never tell a person that you don't have the answer. What I do is I tell the customer, hey, I'm not for sure, but let me double check for you and I will find the answer for you. I do know someone who has the answer. If you could just hold for me for one moment, I would definitely get back to you and make sure that you answer is your question is answered completely and accurately. Last time you want to do is to give out incorrect information.
