Upsetting - will never use. I feel robbed

Completely dishonest. There was a scratch on the rim, can't say for sure it was me or if it already was there, and they were going to charge me over 500 euros. It was explained to me that because the car had a sport package, I just wanted a basic cheap car, the rim was expensive. Not believing the employee I asked to see the breakdown of the cost, all of a sudden the price was 200 euros plus a bunch of hidden fees, such as a 60 euro administration fee?! well this is happening, he is talking in Portuguese to his co-worker and I can not understand what they are talking about. I really feel like I got swindled. DO NOT use - there are a lot of different car rental companies that you can use

They were fine
