They stated I am being sued for a payday loan that I received and did not pay back. I have Never received a payday loan.

They say that they have personal information, like my ssn &bank acct #. They threaten to have me served at my work. They will not provide me with any information, only constantly make threats.

How do I get them to stop calling my work?! This is a headache and something should be done to get these people to stop calling!
