Taken Money by the Bank

I have been retrenched for the whole year with no salary and made arrangements them so that my first pay shouldn't be taken all and now when i got paid. They took it all and i don't have money for rent and transport to work. What kind of a banking system do they use cause it's not my fault to be one of the victims of Covid- 19 .Our banks not the for us they in it for themselves.Let's all boycott banking at them.
