No one getting back to me

On the 24th of December my card was used in 2 unauthorised transactions, although I had personally locked my card from any use on 29 November via the banking app. Upon receiving notification from Absa that there was suspicious transactions on my account, I immediately took action, contacted the ***** department, a case was opened, I sent all the required documents to Absa (affidavit, police case nr) and have been following up weekly, but no one can give me any feedback, the investigator does not provide me with feedback and when I call the ***** department I am told the investigator will call me back and he never does. I need my money back! I need to know what is happening with this case and when it will be finalised! How long before Absa will actually tell me what the hell os going on??
