My Insurance company paid for rental from February 5 2016 to March 9 2016. I was billed $957.00. The corporate office removed $410.00 for illegal personal insurance that is not mandatory, but refuses to credit over $547.00 back to my account. Have proof of double billing. Also, filled up gas tank at station one block from return center. Was charged $18.00 for Fuel it didn't need.
