Paid CLP $184,473 on July 2 for the car rental, but when we arrived to pick up the car on August 4, we were charged the same amount again, as if the initial payment had never been made. On top of that, we were charged 250% more than the original rental price. This was a very disappointing experience and extremely poor service. We will never rent through Kayak again, and we request a full refund of the amount that was paid twice. Additionally, we had a flat tire during the rental period and were left without the car for two days because there was no spare tire available. The situation was further complicated by issues coordinating the insurance, delays in the response from the providers involved, and a lack of adequate assistance from Europcar. Overall, this was an extremely frustrating experience, and we expect the duplicate payment to be reimbursed promptly.
