Is the car rental business the most dishonest? Or do I not understand the nature of their billing?

<p>I rented a car through Hertz - on 2 occasions in the past I was overcharged on fuel and got the money back after a fight! This time I rented a care agains for 12 days. The rental confirmation states the final amount to be paid is R3013.00 - I assumed petrol would be added - in this case just ofver R300,00 and it seems correct. However the final bill comes to R 4599.05 - R 1585.69 more. The bill itself does not explain this inflated amount as nowhere on it does R3031,00 appear. Mr Yakeen Albertyn a Customer Relations Administrator informed me that R3013,00 was an estimate - an approximate amount. Now in what dictionary but that of Hertz does "final" imply meas or lead to infer "approximate"? I have cancelled my September 12-day reservation and will never again use the company - the car rental sea is full of fish! I must add on taking up the reservation the person assisting me was rude - it was not my fault that my plane landed 3 hours late! Secondly - I am South African and an AirFrance frequent flyer and made the reservation through that site. The over R10 000,00 deposit was outrageous and I had the distinct impression - as the booking was in French and done though that website - that the person thought well this is another European with Euros! I feel ashamed to suspect that foreigners coming here on business or for tourism are seen as fair game as "they have money".</p>
