Bad service

They put my account on hold.Due to a client that stole her mother's phone to pay me.And said that they are investigating me for *****.I submitted my affidavit and certified ID and was told they will call within 14 days after the investigation which they never did.I then went to the branch and the report was that i did not mention the owner of the account i only mentioned the daughter and they do not know the daughter because she's not their customer. And told me to go get another affidavit involving the mother.But how do i now go back and change my original statement into a false one.Because i was not in communication with the mother but the daughter?I just need them to open my account so i can have my money back and close their account. Thank you.
