Account blocked

My account has been paused(blocked) for almost 2 weeks now, I have called to many times regarding this issue but I have gotten no assistance. The only information that was ever given to me was that i received funds from a reported account from another bank. The amount was only R400. Right now I have my whole month salary locked up leaving me and my family in a tight situation. I have asked to in contact with the investigator more than 5 times but that has not happened till this day. From the 26th of June till this day I have not received a call or an email from DISCOVERY BANK explaining why my account has been paused. I’m very disappointed and mad, I’ve always believed they cared about their customers but clearly I was wrong. I need my funds ASAP and I will not stop until I get what’s mine
