Navient is calling me almost daily regarding my XXXX yr old daughter 's student loan debt. She does not live with me but they are calling my mobile number ( even on Saturdays ) in spite of my requests not to be called and informing them she is not a household member. 
I refused to cosign for her XXXX XXXX loan and do not understand why they would provide her funds when she did not qualify on her own. 
Her father says he agreed to help her with a loan but does not recall signing an application and requested a copy of this. Navient states he did sign but copy has not been provided. 
He has explained to Navient reps she is not a househd member, is unemployed and only had part-time employment prior to this. He also reported he was a XXXX, but recently retired after having several bad crop years. 
Several months ago when questioned about household income, he disclosed to a Navient rep that I received retirement benefits. Since that time Navient is calling me. Can they call after I requested not to be contacted? Can they call me if I am not a cosigner? How did they obtain my mobile number? Called ID displays call originates from GA & has a XXXX area code-is this legal?
