Europcar ********ly holding back car rental deposit

Europcar holding my deposit of R15 204.00 after claiming I damaged the car. Not providing any invoices for the repairs they claim I am responsible for. They simply ignore my emails and requests, and just ********ly holding back my deposit now for 2 months with no communication. I have been renting cars every month now for 10 years and for the 1st time there is a damage dispute, and it turns out to be an absolute nightmare.
