I was making regular monthly payments to one of XXXX XXXX collection agents. Then Navient took over, stopped the payment and I began receiving numerous threatening phone calls. I filed a complaint with the Better Business Bureau, a Navient advocate responded & said they would respond to me personally, which they did after a very long time. This man phoned me, but whenever I tried to get back to him, he never picked up and he did n't return my voicemail messages. The BBB case was closed, unsettled but put on file. After this, I began receiving threatening calls from the same nasty female Navient rep.
