Not happy with service

I rented a car on 04/06/2024 and returned it on 11/06/2024

I was promised to have my deposit returned within a week.

Nothing has returned into my account When I called in to their call centre on 25/06/2024 I was advised that the Durban branch had not sent my banking details for the refund to take place hence the delay .

I am disappointed with the service
