Multiple calls from this number. Callers have identified themselves as Jay Harris, Tracy Daniels and Mike Peña. Callers claim to work as investigators for United Firms, callers refuse to provide mailing address, phone and fax info for the company (searches for a company by this name have returned no results). They say I need to provide my address so they can discuss the "formal claim" that has been filed against me, or the "criminal charges" which are being filed. They claim that they'll arrest me if I don't call another number and pay them. They claim that I am being sued or being criminally charged for fraud due to failure to repay an internet payday loan. They call multiple times a day. This is a known extortion scam and I continue to log all calls through an open complaint with IC3.gov.
