You are one of the lucky ones who did not fall for their BS.  Good for you!!

Yes they are definitely a scam.  Do not give them any money.   The fact they have your SSN is likely due to some company you've done business with didn't have adequate security.  The best thing you can do is to protect yourself by putting a permanent fraud alert on your credit file.  You can typically sign up for a service with someone like Equifax or do it manually which will require a bit more effort - calls, writting letters, etc.   The fraud alert should prevent anyone from opening a new line of credit in your name.  I'd make it a habit to monitor your credit file going forward as well.  Good for you for blocking their # - best way is to not get the calls at all.   I'd also file a police report and a report with the FCC and FTC on the phone # they are using.
