I am disappointed about the method the Discovery bank use to dissolve matters of their clients, in this case me

I have an account with Discovery bank,my account was blocked, hence they told me,standard bank reported to them that my money was *****ulent suspicious, I closed my account with standard bank,Discovery wanted from me the source of funds and police affidavit and submitted all the documents they requested from me and today they tell me that ,they are going to reverse the money back to standard bank hence it is standard bank who complained, I feel unfairly treated by the bank i love so much,how do they return the money to the bank we have divorced, why did they need the source of funds and affidavit if they knew they won't release my money to me,yes the account they will unblock and give the account back to me,not the money,I needed both my money and my account
