Refund Process

I'm extremely frustrated with the inconsistent information I've received from Avis regarding my refund. After returning the car undamaged on January 19th, I was told the refund would be processed on January 26th and would reflect in my account within 7 days. However, when I followed up after the 7-day period, I was informed that the payment was made on February 3rd and would take 96 hours to reflect. It's now been over 216 hours, and the refund still hasn't appeared in my account. Given the advanced banking system in South Africa, I expect a more efficient and transparent process. I'm seeking clarity and resolution on this matter.
