Not happy at all

I would like to understand why Avis is making it so difficult for me to get my refund back after I have long returned their rental car and waited for the 7 days they told me to wait for and yet still when I make follow up on when will I get my money back, they tell me stories that I don't think I need to hear. I made a call on 11/03/2025 in the morning to understand what is the hold up and said they are waiting for the branch "Rustenburg" to give them documents, i made another follow up today again 12/03/2025 and they still tell me stories and tell me to wait another 7 days for my money. What the hell is the problem here to just simply give me back my money? Why the back and forth? I did my part and why am I still suffering for them to do their part? This is really annoying because that money I also need it. This policy is frustrating, because you go and rent and car, you pay and they give you the car. But when you return it, you don't get your money but they get their car back. I am really frustrated right now and not happy with their service at all. To think it's not even the first time going through this with them but this time around I am enough of this nonsense and just want my money back asap. I collect the rental car on the 22/02/2025 and returned it on 01/03/2025 even to date no refund 😑.
