You wrote they were willing to do it in their plane. It makes a lot of
sense when an instructor wants to do spin training in a plane he
actually knows. On the other hand, it's a very bad idea to even consider
spin training over gross. My sympathies are for the instructors.

The shady paperwork shows their incompetence and laziness to do their job,

Nothing stops you to look for another school. If you're serious about
spin training (which is a good thing), your best choice is to look for a
dedicated aerobatics school with instructors who really understand spins
in their various modes.
