I definitely agree about video taping the incidents. Also video tape them in the backyard when they're not barking to show that it is the kids.

Also, do not let the kids know that you're videotaping otherwise they'll run to their parents and make something up.

Document it every time and call the office EVERY TIME it happens! Otherwise the complaints will pile up on you and not them and it'll be you that will be forced to leave.
