Contact the three major credit reporting agencies (equifax, transunion, and experian) directly. You are also entitled to one free credit report per year from each agency by going to.

d). In addition to the credit report itself, you should request a copy of your credit report over the phone, using an agent. Call equifax, experian, and transunion directly to call (800) 877-742-4957.
