Enterprise Rent-A-Car

On April 8 I rented a car from the company on Pulaski Hwy in Newark, Delaware. I decided to take advantage of the advertised price of fuel for $2.99 a gallon. When the agent returned from the gas station she said "I filled it up". The tank was on empty. I said I told you that I would not need much gas at which time she informed me that we could adjust it on my return. Well on the return it became a different story. She said that the contract would go back to an empty tank and that I am being charged $4.19 a gallon. Therefore, I am paying $56.81 for a quarter tank of gas. Can you image my shock of paying that amount of money for driving a total of 66 miles. My personal vehicle was in for repairs. I have tried without success to resolve this problem but the customer service that I have received has been far from satisfactory. I attempted to file a complaint with the company via the chat room on April 13, promised a phone call never received. On April 14,17,18, 24 spoke with customer service representatives via phone call, each time promised a return call from a supervisor or someone that could help never happened. Again on line I filed a complaint via computer with the support on line team on April 24 again no answer, no contact from anyone. I have tried to be patient as I know I am not the only customer.
