Still waiting for refund of deposit 1 month later

I returned a rental car to Cape Town airport on Friday 22nd April 2022. Even though I had hardly driven the car at all, and it had been safely parked in a private garage in Bantry Bay, I was shown damage to the bumper and told that I was responsible for it. That is impossible. The damage itself looked very old, almost like burnt rubber on the bumper…and it was quite significant, so I definitely would have remembered getting into an accident on that scale. I told them I had nothing to do with it, and my elderly mother who had driven with me everywhere backed up my statement. It is now the 21st of May (ONE MONTH LATER) and I have not received my R9700 deposit back from Europcar. The only communication I have received is an SMS stating that a loss/damage claim has been logged on my behalf. I can’t believe this company’s nonchalance, taking huge amounts of money from people and acting like it’s petty cash - I need that money. As does everyone else on here complaining of the same foul play on Europcar’s behalf.
