Complain

I had an closed account wich wasnt aware what was going on then i had to the branch they told me that my account was used a mule and i have to bring up affidavit and certified copy of an id so that i can prove that i dont have nothing to do with that and i had my savings on the account. They told me that the stop will remain on my account without giving any specific reasons.i kept on visiting the branch they gave me different ways to go but still give the same feedback.. Its been months
