From internet, i was paying for 88 euros and while i was filling with my credit card details the price went up to 113 - while i was signining for the contract at the airport the price went up even more because the policy is that the client pays for a full tank at their price even though the person is sure that he is not going to use the full tank for the all period of rental. Last trap i fell with the agent economybookings.com was that once driving the car i realized that the full tank i paid for was instead 7/8 of the tank so i had to go back to the airport, the operator at the airport parking said that the car i rented had an electrical problem which showed 7/8 of the full tank (a new car pegeout 208). Once the rent contract ended, i wrote to them to ask for a refund of half tank (i left half tank of petrol in the car + 1/8), but they did not answred yet.
