Can a payday lender go after a reference for repayment?

Okay this whole thing is sketchy to me anyway but I would like your thoughts. Yesterday a man from Arcadia Florida calls me and tells me he's from "National Crime Enforcement Department" (no such agency google it for yourself) and that a civil suit has been filed against me. Gives me his name, number and a docket number (Florida does NOT use these Docket numbers). Next wants to verify my info. He has a THICK foreign accent with an EXTREMELY american name. I hang up when he rattles off my SSN and I think he might be predatory. He calls back twice more to har me. I called Arcadia Florida's Civil division and no one knows anything about ANY of it. BTW I live in California. Today I call my mom who informs me someone with the same name and number whom THIS time is a DETECTIVE means to go after her in 2 days if she can't convince me to get back in contact with him for the money I SUPPOSEDLY owe. Let's say this WAS real. Can a lender pose as someone he's not AND can they go after a verified reference for money owed by a borrower?
