Response required on ***** incident

I lodged an incident of ***** on 8 March 2024 but to date have not received any acknowledgement or feedback from the ***** Investigator.

When calling FNB I get transferred but the line just rings and cuts off. I am now told that the investigators do not answer calls and provided an e-mail address to which they may respond when they get to it. Its been over a month, please could I just get some resolution and response.
