Old Navy Neglectful.Sloppy.unprofessional , Internet

Old Navy fraud department was contacted by me after being rerouted 7 times.
Someone opened an account with my SS no#.I had first, been alerted last week by ID.GUARD Dec 2012.When I go in to a store to open an account I have to show
id, then my credit is checked. About fraud alerts, it cannot be put on your credit without a police report to be sent to one credit bureau,they are to contact the other 2.
Old Navy's fraud department claims that they have closed the account, should I recieve a bill (which means criminal has my address)for the 1 item to just throw away it away.This same department claims.There is to be an investigation through Old Navy, but I have not recieved a letter about the account was closed so that I can file a police report.Because of our home being robbed I used that to send to the credit bureau.I feel as though Old Navy is get away driver.
