Easirent

When I hired my car from the Edinburgh Office they offered me two options, one ful/full and the other full/empty. I opted for the latter paying for a tank of fuel when collecting the car. When I returned 12 days later, the member of staff receiving the car said they did not offer a full/empty option but I know this to be untrue, as later that day, I hired from Easirent's Stansted Airport Office and was again offered both options. When returning the car to the Edinburgh Office, I had mislaid my yellow sheet and they refused to look for my records within there system and demanded I return with a full tank.They insisted I exited the parking area and filled the tank before returning because if I didn't I would be charged for a full tank. As it happens since I was late I would have been happy to do so but, as I said they insisted the car was returned with a full tank. Subsequently on my return to my home, I found the yellow sheet which confirms the hire on the basis of full to empty. I have contacted Easirent and, Jason in Customer Services has emailed me to say nothing is due in accordance with Terms & Conditions. The point being missed is, I returned the car empty but they would not accept it until the tank was full, ie I WAS MADE TO RETURN WITH A FULL TANK DESPITE THE HIRE BEING ON THE BASIS OF FULL TO EMPTY. If you can help resolve this I would appreciate it. Thank you. A D Burns
