Hertz car rental cash administration stinks.

Through my Insurance company I rented a car with Hertz. I do not have a credit card and had to physically withdraw cash at an ATM and hand over to the driver who brought my car. I received an email with a form to complete with my banking details for a cash refund that I submitted. After returning the car on 20 May 2022 the battle to get my cash refunded has been ongoing. I phoned Outsurance to follow up many times. I phoned the agent in Nelspruit who told me he'll follow up. I phoned Hertz again today and they promised to get back to me. They do not understand I paid CASH R2000 and after deductions they should pay back R1578.97 into my Capitec bank account. They want my bank to release the money which they have not paid into my bank yet. 🤑
