No concern about my life that is threatened from ppl.

Absa bank is terrible and not taking my complaint seriously. I have send all the requirement they requested for a payment that I received from a customer which they allegedly claimed that he received in his account **********ly before paying me for the goods. And to make matters worse now for me the people I paid money from my end Absa bank blocked their accounts which is causing a life threatening on me. I have being calling them to resolve this but no help whatsoever. The people I pay are threatening my life. I need urgent help.
