Budget Robbing customers money for Damages that exist

I hired a car at Cape Town airport in January 2022 however there was a scratch on the bumper in front and a E Mail was sent to confirm that from them to say no charge , However when returning the car they now started to say it’s going to be a charge when I pulled up the email from Budget they advise they will take it up and confirm , 2 weeks later my account was debited Stating that’s my fault When I sent them back there own email they don’t have any answers as they got the money and keep saying it’s my fault but cannot explain there email that states clearly there was already a small scratch Somebody else then sends me the same email but now the info with the faults on the car is not there which means they know exactly what they done and I have the proof that’s states all the facts To anybody that needs to use budget please be careful of them blaming you for something that was not your fault
