Booked and paid for a rental car in Poland through Rentalcars.com, upon arrival in the airport, it turned out that the Polish rental car companies had changed their policies, requiring a credit card with full first names printed on it. Since Dutch banks don't do this, I had to pay €150 extra for insurance, even though I already paid Rentalcars.com for full coverage. After filing the complaint, and stating that Rentalcars.com booking information and acceptance was not up to date, I only got €50 back. Loss for the customer €100, thank you big greedy corporations, once more you cheat costumers out of money and let them pay for your negligence!! First time booking through Rentalcars.com and right away THE LAST TIME. BE AWARE, you can not hold them accountable for their poor service, negligence or other failures. You the customer will pay, all you get is some useless excuse that they did all they can.
