Sixt review: Caution to renters of SIXT

Caution to renters! I booked a car through Expedia, paying an upfront fee of $487. Initially, the car wasn't available at the airport despite availability, forcing me to spend over $50 on a taxi to the downtown Seattle office. I had bought insurance via Expedia as a precaution, only to be informed at the office that it wouldn't cover the vehicle. The customer service representative (CSR) urged me to buy additional insurance without disclosing the cost and charged an extra $335 deposit fee not included in the Expedia bill. He arranged for me to return the car to the airport when I was due to fly out, or so I was led to believe. I enjoyed driving the Rav 4 for the week without any issues. However, as my departure neared, I received an email claiming I had returned the car late and incurred an extra $76 in late fees. When I contacted the CSR, I was told the drop-off time had been set 13 hours before my flight, which was a clear error. The CSR on the phone was uncooperative and insisted on charging me. Fortunately, the SIXT office staff at the airport amended my drop-off time graciously. Yet, days later, SIXT billed me an additional $123 for airport drop-off and extra insurance costs—services I was initially told were redundant. I was unaware of any airport drop-off fee, as it was never mentioned by the CSR. Beware of hidden charges from this company; I will definitely not be using their services again.
