Account Fraud Help
So here is the story. Someone apperantly has my info and last 4 digits of my ss and has made multiple attempts to call att and requesting to have iphones unlocked and stating the paid retail for them. They got denied at every attempted, and then ATT calls me asking me if i wanted to unlock them but i had no idea what they were talking about, and thats how i found out something was wrong and they told me thats what happend. Now i am pretty scared and don't know what to do. They put a password on my account to make sure no one tries to get in again and i checked my credit score and everything seems to be fine, no loans or anything. How can i get this callers number or info so i can find him or that they can find him?
