No refund due to Covid-19

We have booked a rental car for 23/03/2020 - 29/03/2020 but due to lockdown as implemented by the President, we had to return the car on 25/03/2020 to get to our destination on time. Thus, not using the car for the full period paid. (UNFORSEEN CIRCUMSTANCES) We have been struggling to get our refund for almost a year now!

They keep on telling me that they have a no-refund policy and that we should have informed them prior to the pick up of our intention to shorten the rental days. But how could one have done that? Now if I want to take this further, I must submit a a formal complain on their website. The website is not working, and the agents keep on telling me the same story without any solution.

Hertz SA informed me that should refund us because they have only charged Rentalcars for the days we used the car. I will never use them or suggest them to anyone.
