Discovery insure stole my car and did not pay me.

I have made a claim with Discovery insure since 27 August 2022. I am the legal owner of the car that was involved in an accident. Discovery requested that I send them a letter with my company letterhead to state that the payment should be made in to my personal account which I did. Proof of my personal account and business account were requested and I send to them. My vehicle registration documents and spare key were requested from me and I gave them. A document was send to me to sign in agreement of the amount offered for payment. I was promised to receive my payment on October 18 2022 in writing, to my surprise the money was not paid into my personal or business account. They paid into someone else’s account and they are now ignoring my emails and calls. How does a company make such an error? I have been communicating with Collen Baloyi and I have been sending emails and calling since October 20th request clarification and no communication from him whatsoever.
