Frustrating experience with Woodford Hatfield

I rented a vehicle from the Hatfield branch from 3 to 9 March 2024. I was incorrectly charged almost R500 for toll fees (the vehicle did not have an RFID tag and I paid for 8 toll fees on the N4 with my CC). I could not reach Woodford by phone so eventually visited the branch in person. I was requested to provide proof of the payment of the toll fees, which I have done twice via E-mail. I am still waiting for a response. Customer Care and administration is sadly lacking. I still have not received a statement for the rental.
