Europcar charging R10000 ($665) for small car door dent!!!!

In my 15 years of using various car rental companies, Europcar is the first company to give me my unpleasant encounter. I made a booking on their website to rent a car from Europcar Sandton in October 2021 for two weeks. When I arrived they say that I am at the incorrect pick location, which was not true & I showed them my booking confirmation on email. There was no explanation as to why their system would make this error or apologies, I was made to wait for almost an hour while they "find" a car. When I returned the car I recieved an email from Nick Pedlar the same day to say that there is a dent/scratch on the passenger door. I was advised that it would take three weeks to process the claim. Unfortunately I did not take the liability cover- that's fine, that was my mistake which is proving to be costly. I have had to be the one following up and calling them to get an update of the claims process and repair estimate for 3 weeks if silence from them. Then I get a call from their collections department to say the cost to repair a dent on a Kia Picanto door is R10000 ($665), the amount of R4650 taken from my credit card as a deposit was not enough cover the repairs.

This is where I get extremely frustrated with Europcar. No quotes were shown to me so that I can be assured that they sourced three quotes and selected a cost effective option for the repairs- surely this is standard procedure? Or do they thrive in a policy of selecting the most expensive repair option to make extra money from customers? I have still not recieved an invoice to despite calling them to give them my email address yesterday.

As much as I dont know much about panel beating work, there is no way that the 4cm dent/scratch repair costs R10000. Even if they had to redo the entire door, it still should not cost that much. Did they respray the entire car at my expense? Honestly, I can see why this company has a reputation for being a dishonest brand that attempts to rip their customers off. I will never deal with this company again for business or personal travel and I advise anyone who is looking for an honest, professional car rental company to steer clear from them.
