I booked a rental car in Germany through Rentalcars for US$ 853.87 for a total of 33 days and paid by credit card. I picked up the rental car from Europcar near Frankfurt on June 19. On the way to Cologne, the window suddenly broke. In Cologne, I tried for two days to get a replacement car. However, Europcar could not provide me with one. Europcar in Cologne where I dropped off the damaged car confirmed both on June 21: the damaged window, which prevented me from continuing my journey safely, and the fact that no other car could be made available to me on June 21. Europcar refused to refund me the unused 31 days rental fee, stating that I had booked and paid for the car through Rentalcars, I should contact Rentalcar. After quite a few phone calls and submitting reports and documentation, Rentalcars told me that they would not refund me since I had picked up the car and returned it earlier. The reason was indifferent to them. So I had to pay another US$900+ to get another rental car. I call this fraud, as Europcar or Rentalcars did not fulfill their side of the contract - to provide me with a safe to drive car.
