I'm going to go ahead and close this thread as it already is going off-topic.

For the OP, Hertz did change their refund policy on pts a bit ago:
https://www.flyertalk.com/forum/hert...es-thread.html

If a reservation which was booked with points is cancelled within 24 hours of booking, all points will be returned to the members account. If a reservation which was booked using points is cancelled more than 24 hours before the pickup time the following points will be forfeited: If a Gold member, 50% of the points used toward the booking will be forfeited; If a Five Star member, 25% of the points used toward the booking will be forfeited; If a President’s Circle member, all points will be returned to the members account.
