Price quoted not price charged

We booked a rental with Europcar through [URL Removed] We paid R1800 in advance an no km limit per day was stated on the quote. Upon collection of the vehicle we were advised that the quoted price was incorrect. The actual price for rental was R2292 and there was a limit of 200km per day and a fuel deposit of R3792. We showed the actual quote to the person who assisted us and were advised to take up the matter with [URL Removed] False advertising and no regard for the fact that a quote is binding once accepted! Worst part is that we are on our way to a funeral - absolute incomptence!!
