Managing an account: Checking or savings account

I am the victim of a fraudulent check drawn on my Ally Spending Account. I reported the fraud immediately and cooperated with the investigation. More than one month later, Ally continues to restrict my account, preventing me from accessing my own funds or transferring my balance. Ally has not provided a meaningful explanation of why the restriction remains in place, what investigative steps remain, or when the restriction will be lifted. I am requesting that Ally either ( 1 ) remove the restriction immediately if there is no continuing need for it, or ( 2 ) provide a written explanation of the legal and contractual basis for the restriction, the status of the investigation, the expected completion date, and release any undisputed funds.
