Universal Debt Clearing Inc Threatened me with legal action for a payday loan that I did not apply for or receive and put my ssn in an unsecured email Internet

I was contacted via email from a company thst states their name is Universal Debt Clearing Inc.  They threatened legal action for a payday loan they say I received in the amount of $1, 140.57. 

This is a scam in that the email has so many grammatical errors and the fact that I know I never applied fora payday loan.  This email did include my SSN which is alarming in how they retrieved it and that they put it in an unsecured email.

The email did not include the persons name that sent the email, a company phone number, or address.  I did not reply to the email and when I googled their name, I came across apparently many other victims.
