I keep getting calls from this number, but I don't answer. Woman left a voice message saying she was from Navient (they handle student loans) and they are looking for Dominique Coska. I received calls related to that name about 3-4 years ago. These calls started a few days ago AFTER I blocked another harrassing number - 202-899-1319 - so there is a chance these are related. I wish someone would look into this mess and throw these scammers into the slammers!
This is Navient (https://www.navient.com/); they manage student loans and are likely calling to collect. They've called a lot and I know I owe them money but it is still fairly annoying.
