Rentalcars and Avec Deny Paid Rental Over Fake Credit Card Excuse

I rented a vehicle from Avec for April 16–18 through the Rentalcars app for $121 and paid in advance using my credit card on the app. When I went to the office at Sabiha Gökçen Airport at the specified time to pick up the car, they checked my Findeks (credit) score and, despite my score being high, used it as an excuse to refuse to hand over the vehicle.

Although I had no credit card issues whatsoever, I later learned when speaking with Rentalcars that Avec had entered a note in the system stating, "The vehicle was not delivered because a valid credit card could not be presented." On the exact same day and time, I rented another vehicle from Avis; Avis ran a Findeks check, took my credit card information, and handed over the car without any problems. This clearly proves that Avec's excuse was completely baseless.

As a result, they failed to deliver the vehicle, unfairly pinned the blame on me, and still collected the payment without providing any service. I consider this a professionally executed scam and an unjust enrichment.

I demand an immediate and full refund of the $121 I paid, as well as the removal of the false "valid credit card not presented" statement entered into the system against me.
