Nedbank incomplete services

Greetings have received a call regarding my fixed deposit and have all information. Call cut off tried calling back ********** 000. They transferred me to investments again and call cut off again. Cannot understand you have my details that is email adress and po box address. Yet you have not sent me an update or reminder instead of calling other parties. I do have a unique identity number like everyone else. Have also in the past several times attempted to link this fixed deposit to my business adress.
