Cheating customers

I hired a car with Europcar for the 31st of August over the phone i was told the car comes with 200km. on a separate day called the center again to confirm if the car came with the 200km per rental or the km were per day also if the car was manual or automatic as i did not receive any document confirming my rental and i was informed by the agent that he car was automatic and it came with unlimited km. Collected the car and used it for the weekend bearing in mind that the km were unlimited, when i received the invoice i was charged R432.90 for additional km and i then inquired why was this the case because as far as i knew the car came with unlimited km and they informed me that 200km was confirmed when the booking was made and i informed them that i had called again to confirm the km and the whether the car was manual or automatic and was informed by their agent that the car has unlimited km and i then requested call recording of which they do not want to provide to me because they know and they have heard from the recording what was communicated to me but they still refuse to own up to their mistake.

That was not all the inconvenience i received from the company on 23 September i returned a car i had hired at PE Airport and once again when i receive the invoice i noted there was a fee of R378.05 charged for filling up petrol. I do not understand how i ca fill up a car at a petrol station opposite the airport and then be charged that amount of money. i have email my petrol receipt and as expected they are not willing to assist. This s very unprofessional.
