Left a voicemail saying he was Jonathan Blackwell and has a matter directly involving my social security number. Never said my name or SSN or what he was calling for other than a 'direct matter'. Gave me a reference number when I call back. I called back, got hung up the 1st time and the 2nd time - someone answered "can I help you". NO company name, no identity - they are now blocked.

Received a call from this# claiming to have a case me.
