Nice work....super sleuth!
How can anyone live with themselves screwing over a church of all places. It does sound like that admin was not doing her job or there were no checks and balances. The bad part is it would be hard to prove that the meters were rolled back. But if I was in the situation I would cost justify how much those units were and be sure they were NEW if our organization wanted new. How do you not know if you buying new or used. Like you said if you sign a lease with the NEW box checked and you get used items then you just committed fraud. I would have her check the actual lease and have them put that dealer on the spot. Then you can offer to take over service on the fleet. That way you are being honest with her.
