Yes.
Mr. Firth, I heard, “I have the information but I'm not going to provide it right now. I'll provide it later in writing,” which is different from, “I don't have the information now.”
I think you need to be very, very clear with your answers and say, “I don't have this information available to me now; I'll provide it later,” or, “I am not willing to provide it at this time.”
