The confirmation number doesn't go to an e-mail, it shows up on the page after you finish the hack report. If she didn't get one then that means the report didn't go through. If she kept getting the same form over and over after hitting submit, that means the page was refreshing because she didn't fill it out correctly. If that is the case, she needs to fill out another one. Make sure she fills in all of the blanks. If she doesn't know an answer, she needs to put "I don't know" or "N/A". Once she gets the number, make sure to tell her to hang onto it so she can PM a mod with it if she doesn't get a reply after four weeks.
