Navient is a student loan servicer associated with Sallie Mae. They've been calling me too, leaving messages for me to call them back. I'm retired and never had a student loan. They seem to be trying to reach my niece, who has never lived with me or used my phone #. Other posts say that they try to get relatives to pay for the loans. Don't know if that's what's going on but I relayed that they were leaving messages to my niece, who said that her father was handling the matter (whatever it is). I picked on on the 5th such call after doing some research here and elsewhere. They announced that the call may be recorded. At that point I stated that California is a two party permission state with regard to call recording, that I don't give them permission to record, and ordered them to turn their equipment off. They asked for my niece. I stated that there's no such person here and the call ended. Doesn't matter if they're in a different state. They're vulnerable to fines and/or jail time if they recorded. Already been adjudicated.I got a call today from 712-884-3038. See my entry here about that number. It might be related.
