Just received a call from them, wouldn't tell me what kind of company they are without me verifying my SSN/DOB/Address so I denied all and said unless you can tell me who you are I can not speak with you. Woman responded that they listed me as a refusal.
I just got a call, same thing. They won't tell you who until you verify your social but it's 'an urgent business matter'. Because they generally send barely literate people to try and deliver the most urgent business news.
