Avis car rental poot customer service

On 16January 2023 i rented an avis vehicle that was arranged through my insurance. Upon collection of the vehicle i paid in R2500 cash deposit that was going to be paid back yo me 7days after i returned the vehicle. The vehicle i received had a bad smell that i had to have it washed at a car wash. 23 January when i returned the vehicle i mentioned to them about the smell in the car and i also filled in the cash refund form and wash told that the money would reflect in my account after 7 days. On Thursday the 2nd of February when i didn’t receive any money, i called them and asked them what the hold up was. I was asked for the reservation number and told that they will call me back. Thursday passed without a call back and Friday i called again. I was asked foe my reservation number again and was then told that the money was already process that Friday. Today on 6 February when i went to the avis branch to enquire what the problem was, i was told that my money is only being processed today and it will take 3-5working days to reflect in my account. In 2018 i experienced the sam problem begging for my own money. It’s been more than 7 days and my money is still in process. Please Avis sort out your admin and financial department and have my money deposited into my account.
