Please assist

My account number is ***, I have had this account since January 2004. I’m just hoping that Standard bank can find a way to assist me and meet me halfway on this one. I used to work for South African Airways, I have been recently retrenched. Before I got retrenched I did not even know that there was something called retrenchment insurance. I have recently been informed about it. I have also discovered that my account’s retrenchment insurance only covers disability and death, unfortunately, the most important part of the insurance is not available for me since I’m not disabled, neither am I dead. My main challenge is that at the moment my account is way overdrawn and has gone past the overdraft limit. All my attempts to get assistance from the bank are not yielding any results. I just need to know what should I do in the meantime whilst my accounts accumulate more interest as I’m no longer employed, I hope this is not too much to ask from a bank that I have been a customer to whilst I was still at school.
