Requestor reply not appended to request

Hello.
 
I received a help desk ticket yesterday.  I needed more information so I clicked on the button that says "Reply" and I emailed the requestor.  She responded back to the email but I never received it, nor does the request indicate in any way that she replied.  Can you please advise?
