My father has been dead for XXXX years and was removed off the loan while XXXX XXXX was servicing it. Now I have Navient calling AND adding his name BACK on the accounts. I have been thru all of this with XXXX XXXX firm over a XXXX They ( Navient currently ) threatened me with seizure of property, that they would NEVER stop calling. I sent a cease and desist letter certified and already received, advising no contact BUT regular mail and Im still getting emails. I also requested proof of debt that I have yet to receive. Still less than 30 days though.
