I also got an automated taped call saying I need to call due to a legal issue. I decided to erase the message and ignore. I would think that if legit I would get an actual person leaving the message with the name of the company.

Recorded call from a Harrison Clark from the SSA reflecting that my SSN has been suspended because of suspected fraudulent/criminal activity and to call their emergency helpline back at the same number they call originated from. This is the third time they have called with different phone numbers propagating their scam.
