Trustees are attorneys who represent the United States government (executive branch). Their job is twofold. First, they are an officer of the court, and part of their duty is to make sure you are complying with the bankruptcy laws. Second, they also are looking to see if they can take assets from you to satisfy the claims of your creditors.
A Trustee is not your attorney, and they do not represent you. They are actively trying to take assets from you. If you call their office, they will not talk to you because they represent the government. If you have any questions about your case, call your attorney.
