I have rented with Sixt before and have always been happy until now.

At the end of May I needed to rent a car for only one day in FRA. I went online and via rentalcars.com booked a car from Sixt. The car I reserved was a mid-size with unlimited miles for 52,50 Euros with taxes and all 74,97 Euros. On day of arrival in FRA all went well and I was in my car and on my way in short time. The next day on my back to the airport I had a hard time finding a gas station and was getting nervous about maybe running late I turned the car in with a 1/4 tank of gas.

I checked my American Express bill a few days later and was shocked to find Sixt had charged me $528.31!!! I thought it had to be a mistake and sent an email to Sixt and they in turn asked for me to send them a reservation number. Yesterday I received a email stating,"We have corrected your invoice according to the drop off date 30th May today. The new invoice amount is 306,67 Euro." "Dear Mrs. ******, I will be happy to investigate the bill item ?Petrol, inc. filling? for you also. Please send me a copy of your fuel receipt, quoting your bill number and marking it for my attention, either to the fax number below or as an e-mail attachment."



I am dumbfounded by that response. They want to charge me over 230 Euros for 3/4 a tank of gas?
