Fox enterprises Fox enterprises filing a bogus claim against me Internet

 I was contacted by a litigation service stating that their client Fox Enterprises filed a case against me for a payday loan that was supposedly taken in 2013. I asked the litigation officer for information as to the case and all she would say was that a loan was taken out under the last 4 of my social security number. I researched the company and found approximately 6 phone numbers list and all of the were either no longer in service or was for an entirely different company. I have never received any correspondence in this matter now was ever contacted by Fox Enterprises. When asked for signed forms and documentation, the litigation officer only gave me options to pay or wait to be served by the local court.
