Complaint about service delivery at bank (Capitec)

I would like to express my disappointment with the service I received from Capitec Bank. I reported ***** on my bank account, after many attempts of me contacting the bank to get feedback I was told the case was closed and my money couldn't be recovered. I was not called by the investigator to ask me any questions about my incident. I really feel that there is no care from the bank about my funds being removed from my account. When visiting the branch after receiving messages that my ***** case was closed. I was told that if I have a complaint to send an email to the complaints department, they can't help me with my ***** case. I am not very happy with the service I received.
