Deposit not released by Avis

I hired a van at Avis on 30 Nov 2024. The vehicle was returned on 1 Dec 2024. I received my invoice on the 4th, the deposit amount has still not been released. I have called the branch already and all they can say is that they contact HO who then instructs the bank. The amount is still pending on my credit card. I’m not looking for someone who will call me to tell me that the hold doesn’t mean the money is taken. The fact is that amount is still pending and is not available for me to use. Since when does it take 2 weeks for a deposit to be released via a credit card?
