Re-appealing a judgment to confirm the first instance court's judgment

I filed a criminal case for physical domestic violence, defamation, and threats made towards me in December 2018.

After a long process in the public prosecution and evidence collected as well as witness testimony, the first instance court gave a judgment to the accused of 3 months imprisonment, deportation and a 10K fine in November 2019.

The accused appealed the case and, on ALL three charges, he got "innocent".

I made the request to the public prosecution to re-appeal the appeal and send it to the cassation court. They sent me a rejection SMS 1 day after I made the request. How can this be? The public prosecution is supposed to be my defender in this case.

I do not feel safe as a single woman living here anymore. It is not easy for me to leave because I have children who attend school here and he threatened them as well.

I need to know if there are any steps I can take to make the cassation courts take this seriously and look at the file again.
