********!! Rather rent a car elsewhere

Unbelievably sent me an invoice and charged me for 15 Litres of fuel when I filled up before I dropped it off. They are ripping customers off over and over again and it baffles me how they are still in business as they are ******. When I queried this they were adamant that they were able to fill the car with 15litres after I just filled up with almost 30litres.. and it’s a 35 litre tank. THEY ARE ********!!!
