Refund of monies swiped ilegal

Hi I got ****** Saturday evening February and all my belongings were ****** because it was a weekend I couldn't manage to go do a aim Swap at my Vodacom branch of which I did the following Tuesday due to financial constraints,when i did the SIM Swap I realised that someone was using my card at different shopping centres of which I went to the Police station to open a case and they managed to pull the Footage and we indentified the culprit of which he was arrested and convicted to 5 years and I have the footage in my possession as well but to my surprise Discovery does not want to refund the monies that were ****** ******* they I reported the case late but surely the conviction serves to be the best proof of all..All I want is discovery bank to refund those funds either way because some financial loss and the conviction of the person is evident enough that's the proof that the person was using my cards the other banks have resolved everything.
