First National Bank Has Let Me Down.:No assistance regarding my ***** case

I'm highly disappointed by FNB bank and seeking for intervention regarding a ***** case I launched during the month of March 2023. Till date, my bank has not responded regarding the alleged crime . I have been banking with FNB for more than a decade and I can't believe their attitude towards mismanagement my case. They assigned an investigator called Nhlamulo Baloyi to assist me. I tried calling him and emailed him for feedback, never did he respond. Then i escalated the matter to Yoliswa Dolisa, who promised to give me feedback, till date. Last week Friday I tried again reaching out to their team leader Tween Lioni, she's not answering our mails and calles from the branch bank. This left me frustrated and worried. I opened a ******** case with the police regarding this *****. And my bank can't help me and refuses to give me a feedback.

Please do intervene as I don't know what to do.
