Poor service from Sanifleet Jetpark

I rented an NP 300 bakkie from Sanifleet in DR Vosloo Jetpark on the 5th April 2022. I returned the bakkie on the 4th July 2022 and was told I would receive my deposit in 21 days. I contacted them as I did not receive my deposit and was told that the staff neglected to send through the paperwork to their finance department and it would take another 3 or 4 days to get my deposit. This is absolutely poor service as all payments are taken immediately for the rental and then we have to wait 21 working days to get our deposit back and the company can't even manage to do that.
