I recieved a call from a private number, saying they were with Navient. Saying they were trying to collect on a student loan i have. I have never gotten a student loan - EVER. When I refused to give them my info - they gave me a fraud number, but no one answered at that number. I want to make sure no one has used my info and I dont have a student loan. How do I verify this and not give my info to just anyone. thank you
