Former Property Manager not releasing tenants security deposits

Wondering how I should proceed in my situation. I had a falling out with my former property manager when I asked them to do a kitchen remodel, when that remodel was partway done, the incompetence of the remodel showed, with glaring defects, illegal work, and skyrocketing cost. Shortly after terminating them from the kitchen remodel, our property management agreement ended (for the better as they didn't manage the property at all).

After the agreement ended, we signed a new property management agreement with a new company. The former company will not release our tenants' security deposits to the new company. How should I proceed in this situation? The property is located in Virginia.
