I got robbed

Firstly I called to find out what I needed as I was booking for the 1st time. The gentleman said nothing as I'm booking on line that when I get to the airport I just present my ID and the card I made the booking with. Got to the airport they needed documents that I had to run around for and going up and down. 2 hours later I went back and only to find out I was also lied to with the insurance I was told that if the are no damages I get my money back only to find out at the airport that it's a lie. I had to take additional insurance with Bidvest car rentals. I called Rental car.com the lady could not find me on the system all of a sudden but they took money from my account. I tried calling for hours no with no help. I feel robbed. I will never use them again and my loved ones too.
