That is VERY good advice, and DO involve the United States Parachute
Association before you get desperate! USPA has been historically
responsive in mediating situations like this (it is part of their
charter), and skydiving operations are smart to cooperate.

(For insurance and other reasons, almost all jump operations are USPA
group members, and must adhere to a minimum set of rules to maintain
that membership.)
