received call from very unprofessional man, coughing and mumbling-asked for me by name, then wanted to confirm my lat 4 digits of social. When asked for details of his company, he said Glass Capital. When asked what he was calling about, he said "a personal business matter".
I called the number back, got a woman this time, she said the same things. When I would not confirm my social, she got abrupt and said "I am going to have to terminate this call".
