Electric company and new tenant

[Callie Mahoney]

The electric company has required my new tenant to make a huge deposit due to 'previous late payments'. The company renting my property already has 86 rentals in the state and mine is the 87th. The company renting my property has not had this happen with their other 86 property rentals. 

I record all conversations. I have records stating the deposit requirements for turning on electric are completely different than this situation. Just because they are my tenants there is a different requirement than ever before?

 Has anyone experienced this before? What would you do in this situation?
