They called me and asked me to verify my date of birth, SSN, and phone number. They wouldn't tell me why they were calling at 9pm either. I hung up on them. I'd advise everyone else to do the same and DO NOT give out your info.
I received a call and it was a recording that keep saying "please continue to hold" over and over with musi playing in the background. Hung up. Suggest you do the same.
