Emotionally devastated and ill-treated

I made advanced payment arrangements with a call centre agent at Standard Bank as I am currently unemployed. Subsequently their credit department ignored / overlooked such recorded arrangements and dipped into my bank account without my permission, taking 85% out of my meagre savings account with out consulting me. Despite me being out of work at the moment without any source of income, all this happens in the middle of being bereaved by my poor unemployed cousin brother who suddenly died from an accident. I have not had any income or money in my account for sometime and the money into which they forced themselves into was a meagre R12110 which came in from a longstanding SARS income tax claim some of which was meant to contribute to the burial of my poor cousin brother. I linked with the call centre to amicably resolve the issue, got referred to the Branch which has been industriously and patiently assisting me linking me to the call centre people. The latter became the beginning of my emotional torture being ill-treated and bul**** by one agent to the other for almost 2 weeks in vain until now.My cousin brother had to be buried regardless and my kids continue to struggle.
