They are scam artists. Stuck me with a diesel car which wasn't on my rental agreement, then charged me an extra tax ("pollution tax") when my agreement said all taxes and surcharges were included. We discovered about 45 mins. after we left the rental facility that we only got 1/2 a tank of fuel. Called the company immediately who told us to email them the photograph of our fuel gage. Never received a response. We had only driven about 80km (about 50 miles) when we noticed. I drove further than that on the return and it only took about 2 gallons and cost about 10Euros for fuel. When I returned the car with exactly the amount of fuel I got, they argued with me, blamed it on me and then charged me for fuel and a fine. They pushed it off to customer service when it was their own people who told us to email THEM. I will be disputing this with my credit card company.
