Hertz South Africa disgusting customer service!!!

I WILL NEVER HIRE A CAR FROM HERTZ EVER AGAIN. I can’t believe a big company like HERTZ does not respond to customer issues I have sent two emails and I have went personally to their office in OR tambo to query the issue why am I being charged for damages when I brought it to there staffs attention before I took the car as well as when I retuned the car that the rim was scratched. The office told me they going to escalate the matter till now no response to that or my emails disgusting customer service!!! In the last 2 weeks i traveled 3 times first time I used Herts after that I used WOODFORD twice WITH NO ISSUES WHAT SO EVER!!!! HERTZ for a big company very unprofessional
