Shocking Lack of response for a fee incorrectly deducted from my credit card

I rented a car from you in December 2025. On 20 January I received notification that R405 had been deducted form my credit for a 'Traffic Fine Admin Fee'. I called your offices and the fine was in Johannesburg. I received an email back from Francis Uriel your fleet administrator on 26 January acknowledging error and saying the amount would be refunded. The email from Francis: "Good day P***, Kindly be advised that I have disputed this fine with the authorities. Trip report proves that this vehicle has not left Cape Town , we will credit you the admin fee billed to your account. Thank you for raising our awareness on this matter. Kind regards Uriel" I called last week (16 February) and spoke to Uriel in person after weeks of unanswered emails. I was promised that that the amount would be reimbursed before the end of last week. I have still not been reimbursed! It has been over a month since the amount was INCORRECTLY deducted from my account. You have acknowledged that the fine was incorrect as it was impossible that I was in Cape Town according to you GPS recordings. I am writing on this platform to try recover the amount. Should this not be paid back I will also be reporting this to the Motor Industry Ombudsmen and the Southern Africa Vehicle Rental and Leasing Association.
