Credit company west assist managment

Lady called from this phone number 469-777-4244 did not say and would not say what company she was with even though i verified my name with her, she continued to try to get me to give her info like date of birth, address and ssn told her would not release that info over the phone and then she told me she could verify my address but why would i verify or give anything without them disclosing what company they are calling from (so stupid)
