You need to move on. There is no recourse for a purely bad decision.

How can I get my leasing office to pay for storage fees for a tenant's rental car that towed on their premises?

Unfortunately, they are not at fault because their office was closed and you parked in a spot knowing you could be towed. Chalk it up to a life...

Get a real estate license. It does not take that long nor is it expensive and would likely be useful in your business.

Do i have to pay a contractor i fired before they did any work?
