ACE Car Rental Refused to bill car rental Insurance Indianapolis Indiana

I rented a car at the ACE at Atlanta airport this month.  I had a minor accident when a car sideswiped my car as I was stopped in a median waiting to go into traffic.  When I arrived to drop off my car I missed my flight because they were taking pictures of the damage and completing a report.   I had purchased car rental insurance when I reserved the car with Priceline.  So, when I got home I completed the forms to have ACE be reimbursed.  All the insurance carrier needs is a report about the accident from ACE. 

This is where my troubles have begun.   When I contacted ACE, I was told by the repair department they will only deal with my automobile insurance, not the car rental insurance I purchased.   They stated my insurance is primary, however, even the car rental insurance company is stating they are primary.   The car rental carrier will only pay for damage to the rental car, which is fine because the other person car was not damaged and there were no medical expenses.  I will not give ACE my automobile insurance info because I think they want to add some upcharges and collect more money.  

The car rental insurance has agreed to pay all they need is a record of the damages which are less than $1000 but ACE will not deal with them.   Consumers buy the car rental insurance coverage so, this will not go thru their insurance.  This whole thing seems very weird to me.  The car rental insurance is willing to pay them but ACE won’t send them a bill.   I just do not trust them.
