Navient Debt Collection Complaint

Navient Debt collection department,

Non-federal student loan Communication tactics Frequent or repeated calls Michigan

This debt is a result of me co-signing a student loan. They call allday long. If you do answer they demand personal information ( last - of ss # plus date of birth ) before they tell reason for call, When I refuse to provide info over phone they hang up and call back within a hour. I have repeatedly ask them to stop calling. I 'm not avoiding the debt, they always get paid. I just do n't want to be harassed.
