How often have I heard bullshyte like this?
Make an allegation and put your name to it.

Watch as they erase their tracks and make the crimes you accused them of disappear.

Cry as the regulator believes it and walks away.
CASA, you have been warned that IAA is a shyteshow. Get off your backside and audit them!
