^^^ NutBrnHair's advice of "sorry it didn't work out" is probably the best advice, but I would be sorely tempted to say something along the lines of "I did everything I could to get recs for your daughter and to help prepare her for recruitment, and neither you nor she ever once said 'Thank you.' I guess nothing I could do could hide from the chapters the fact that you failed to teach your daughter basic manners, so I'm guessing that's why it didn't work out for her."

I'd want to say that, but I wouldn't.
