Avalon Car Rental Deposit Not Refunded

I rented a Renault Clio with plate 07BDD0** from Avalon Car Rental in Antalya from 1 July 2026 until 11 July 2026 and returned the vehicle in good condition on the agreed date. At the beginning of the rental, Avalon took a security deposit of ₺60,000 (approximately 1,100 euros), which I paid by SNB credit card issued in Saudi Arabia. After returning the car, I was informed via WhatsApp that the security deposit would be processed within 21 working days. Despite this clear information, the deposit has still not been refunded, and after that message the company stopped responding to my WhatsApp messages. I have also sent several follow‑up WhatsApp messages and an email to Avalon Car Rental, but I have received no reply and my refund has still not been processed. This situation is causing me financial inconvenience and seriously damages my trust in the company. I request that Avalon Car Rental immediately refunds the full ₺60,000 security deposit to my SNB credit card and provides a clear written explanation for the delay and for the lack of response to my messages.
