Discovery cant protect their clients from horrible service providers!!!

I had a claim with Discovery and as part of my claim I received a courtesy car from Avis. To receive this car, a security deposit of R1450 needs to be paid upfront. I did pay this amount and repairs on my car were finished on the 29th of December, same day i returned this rental car; in the exact same condition I received it. And then came time to receive my deposit back. I called in and was told stories about how the instruction has been sent to my bank and i will receive the money within 48 hours.

Yesterday I ended calling Discovery claims regarding this matter, since this is provided as part of their service. I was told that the matter will be "escalated" and I will receive prompt feedback on this matter, at the time I am writing this, my deposit is still not back, no feedback from Discovery and no one is answering calls at Avis.

If Discovery is going to tolerate this type of service, then they are surely going to be taken down along with Avis.
