Hertz debiting my account without permission

On 18 March 2025, I noticed a debit of R5,359 on my credit card account, with the description "M#HERTZ RENT A CAR PARROW." I did rent a car at Cape Town Airport on 6 December 2024 for three days and paid R1,645.70, as per their invoice. Nothing seemed wrong at that time.

I asked my bank to reverse this new charge, but they advised me that there is a dispute and that I should take it up with Hertz. I emailed Hertz, and Khungeka Tamara Tumalele rep**** that I still have a vehicle and that they cannot provide information about the charges while I still have it.

I informed them that I have not rented a car since December and that the car was returned. I also mentioned that my dad sometimes rents cars and has the same name as mine, but obviously, his ID is different.

After not receiving any feedback, I emailed *** on 19 March requesting an update. However, there has been no response. I reached out again on 20 March and 22 March, but still received nothing from them. The debit has still not been reversed. I tried calling them just now, but after being put through once and waiting for a while, the phone just went dead.
