I Want a Refund for a Misleading Avis Rental Insurance Charge

I rented an Opel Corsa from the Avis Sarajevo Airport location through the Yolcu360 app and prepaid the rental fee with my credit card. After landing at Sarajevo Airport at approximately 10:45 a.m. local time in Bosnia and Herzegovina on April 26, 2026, I went to pick up the vehicle. The Avis employee charged me $389 for insurance but did not tell me that the amount was in U.S. dollars. Instead, I was told that the charge was equivalent to approximately $60. By taking advantage of my lack of attention during the transaction, Avis charged me $389 for insurance on a vehicle that cost me approximately $84 to rent.

Approximately four hours after the transaction, I requested that the insurance be canceled, but no one provided any assistance. I also emailed Avis but received no response. My rental agreement number is 612858363.

I am requesting the immediate cancellation of the insurance and a refund of the amount I believe was unfairly collected. If any portion of the charge was legally mandatory, Avis should deduct only that required amount and refund the entire remaining balance to my credit card.
