Sorry to hear it. But don't do this:
I would call right away. And again,and again, and again. Just like out in service.
When somebody here complains that elders are trying to track them down, or some crazy family member won't leave them alone, we tell them to screen their calls, change their number, and report it to police. He has made a choice, if you can't accept it, at least don't harass him. Try them again in a few months - she'll most likely tell him what happened, and he'll most likely tell her that he wishes she hadn't done that. These things take ages. Meanwhile, go do a lot of fun things and live your life.
