Europcar does not refund money due to Airline Liquidated - Discovery Travel dont care

I am a Europcar customer for many years going back to 2003, On 28 May 2022, I booked car hire and flights via the Discovery Travel app, The Europcar initial fee was taken from my Discovery card as a stand-alone charge of R 969.00 for car hire on the same day, two weeks after the booking the Comair was grounded due to financial problems, this aspect impacted many passengers and car hire customers. My issue is Discovery has only assisted the clients who made booking a week in advance before the airline buckled, they have washed their hands off with other Discovery clients who have lost their money. Europcar has also decided to keep the client's money, yet the car hire company has not liquidated it. I request to be refunded by Europcar and Discovery to have some sympathy for their client's losses.
