Avis not paying back my deposit and threatening me with legal actions

Avis NOT paying back my deposit.

I have been renting monthly from Avis since we returned to SA in Oct 2024 until May 2025 when we purchased our own vehicle.

On May 15 2025 I have returned my rental 1 day before my RA expired and the rental was accepted with no issues ect. And until today 04 June 2025 I have not received my deposit back. The manager at the branch have been kind and somewhat helpful but seems like the departments above him do not care to give back client's money. I had to provide prove of all my payments which cost me additional fees to get statements to prove they owe me money...how is this not on record at avis? On top of that my final etoll account i have received was not my account as the transactions on this account made use of a etoll 300km from me. And now you want to take legal action against me after I have tons of proof I was not using that tollgate.

Avis why are you withholding my money????? I have been a loyal customer for months! Even when I scratch the bumper I immediately went back to the branch and I paid for the repairs. And this I could have easily refused was my damaged but I a honest person!
