Thrifty *****s up and does not fix their mistake

Thrifty is such a disappointment when it comes to refunding deposits. I am an international traveler who rented a car from Thrifty Green Point, Cape Town, South Africa, during the month of December 2021. Thrifty refunded my deposit on 11/01/2022, but into a wrong bank account. I have used the Thrifty online ticket account to make enquiries, I have made several international calls from Australia to South Africa and spoke to many of the Thrifty customer services staff, who all acknowledge that they have the correct bank account number, but still need to do the refund transfer. How long must a loyal customer wait for Thrifty to fix your mistake? You have my money, and it is a large sum of money. Is Thrifty holding off on refunding the deposit because Thrifty is trying to get the money back that they paid into some unknown bank account? This is by no fault of mine. Thrifty, your service is appalling. Shame on you for not doing the right thing by your clients.
