Investigator MIA vol 2

Good day, Once again, I have sent several emails in this regard. When my FNB account was frozen, Capitec also froze my account following an instruction they received from the investigator. After I emailed him, he said I can go to Capitec and ask them to unfreeze my account. I have but they keep saying they need the instruction from FNB. I have policies that are going to lapse due to this issue.
