“Embarasment tactics” should only be used after asking a non-nogaih Rov, (from outside the community) and only in cases where there is no reason why the family stopped paying.”
Just as a point of curiosity, I would love to know the name of any Rav who would be matir embarrasing the children under ANY circumstances involving the parents failure to pay tuition.
Have a Good Shabbos.
