Questionable requirements of deposit payments

I rented a car at Pietermaritzburg Airport and returned it the next day (07 June 2022). Everything was signed off as being in order. I have however, since the 07 June 2022, waiting for the refund payment of the deposit and a statement (I completed the refund form and was promised that the monies would be refunded).

Firstly: Which monies (how much) as the company does not have the courtesy of emailing reconciliation. Secondly, the company has been sitting on my money for nearly a month. Will they pay the interest?

When you call Europcar you are given the excusethat they need to verify your ID number (they took a copy of my driver's license and my bank card)!

This is shocking and people like this should not be allowed to hold onto and work with third parties' monies!

When I called on Friday last week I was again told that my ID number needed to be confirmed. What nonsense is that as the office in Pietermaritzburg took a copy of my driver’s license and my credit card. Further, and as a sign of your more that dilatory manner of handling this matter, I have to date not received any reconciliation from your office. Should this money not reflect by 12:00 of even date and should I not have received the reconciliation, I will then take other steps, all of which will be for your account.
