I got a call from this number as well and its a bill collector for either a Hospital or a Doctors office they wouldn't give me any information on the account until I verified my name and D.O.B. w/ them or confirm my address... Like I told the guy I refuse to give information over the phone to a complete stranger he then told me he would notate the account that I was being difficult I told him to notate as well that I will not give out personal information to a stranger and hung up on him... These are some of the websites I found on them
