Who called from 4085123807

Missed the call. Called back, the lady answered "GNP credit services" or something like that.

Didn't pick up immediately but called back later.  A lady answered and wanted the last 4 digits of my social.  I declined and asked what's this about, then she said that she needs to terminate the call because I refused to "verify my identity".
