Account locked

Last month I received money form a client. As I was busy doing transactions, I noticed that I couldn't send money. Gave me an error that my account has a lock. I caaled the customer care. And the lady assisting me said I should contact the person who sent me the money. Master on a revived an email that my account is being investigated for ***** it will take 42 to 72 hours. Those hours have passed no one has called me at discovery to explain what is going on. The client that sent the money when I called and ask him if he reported the money. He said he didn't. Last week I called discovery bank and asked about my account. The lady then said u must speak to the person who sent me the money. Tell me why is my accountocked for so long. When the email stated that the investigation will take 72 hours. And after that I wasn't informed what is needed on my side. Now I can't do anything my money is just staring at me.
