Overcharge, no response to mails and no refund

I parked at level 4 at ORT on 17/05/2022 for a little over an hour and my parking ticket shockingly was R1020 which I paid. I was provided with an email address to request a refund, which I did. A response was received on Monday (16/05/2022) from Zweli requesting additional information which I provided. My request was referred to Dineshri Aboo who advised on 2022/05/17 that my refund would be processed in 4 working days. I followed up post the 4 days only to receive a request for additional information (which I supp**** timeously). No feedback has been received since then despite me following up with Dineshri. Can I receive some sort of urgency please, I have been patient and cooperative.
