This number called me and a person with an accent spoke. I think they said their name was Michael but it sounded like a woman. Anyway they asked to speak to me and they said that they had a person business call holding on the line for me but needed for me to verify my date of birth, which I refused. They then asked if I was born in XXXX year so apparently they have my personal information but wanted me to verify it before they would connect me to the "personal business" call. I refused to verify anything and they refused to tell me what they were calling in reference to. I don't think its a debt collector but a scam artist phishing for my info.
The same happened to me as well. The "Michael" sounded like a woman and asked me for the last 4 of my social and when I refused they asked for my date of birth. When I refused both and asked what the call was about, they said they couldn't disclose what the matter was.
This man asked for my phone number and SSN, when I said no to giving my SSN, he (suddenly he got nervous and starting sounding like a she) he asked for my first and last name. Then he put me on hold. I hung up getting suspicious.
