Over Charged

I travel maybe 4 times a year and this is only the second time I have rented a vehicle from First Car Rental. In all these times that I have rented a vehicle I ensure the vehicle is full prior to returning it to the rental company. To my surprise I receive a charge over and above the agreed price (never happened before) for fuel. The petrol station in fact is across the road from East London airport. The response is simply First Car sends the vehicle for checking after return - I feel as a company First Car have missed the opportunity of understanding the risk you place with your customers. This is not merely about the overcharge it is about the miss use and abuse that happens once the vehicle is returned. Nothing prevents miss-use and for this customers suffer. A politically answered response adds no value. I can only recommend as customers, that we need to take a photo of the dash and mileage, in the present of First Car Employees, this is possibly the only defense if any. Highly unsatisfied with First Car based on outcome.
