I need my account released today

My account has been blocked by FNB for over a month now and the person who was dealing with my account is Shaun bishop and when he went on leave before resolving my issue I kept calling every week and I was told the matter was escalated to Team Leader Leoni T****i to give to another investigator to assist and they will call me back to assist further I have been waiting for over 3 weeks for assistance and nothing is happening when I call the call Centre they always sending emails to Shaun and Leonie but no one ever gets back at me. I have money in my account that I need to use but I can't because my account is frozen I had to go to lents of borrowing money from people just to be able to get through the month and now I need to pay the money back and my account is still frozen
