Can’t believe Avis

Was debited R4591 on my account on the 18/1/2022. When I queried it I was told it was damage to front door! This was not correct as when I took the car back to CT airport branch a inspection was done and everything was fine. They told me that this would be resolved in 5 working days and I’m still waiting. I have phoned customer care numerous times and they keep either putting me on hold for ages and then I get cut off. I was told by Thabo that he will send email to relevant people and cc me in and has not I keep getting told that a manager will phone me and does not. My reference number is ***. So disappointed
