Who called from 2762621723

Claim that I owe them from a payday loan from 8 years ago, threaten a judgement and garnishment. Left me on hold for 27 minutes when I request to speak with a manger.

Received a generic recording that did sound somewhat official claiming that this was my last day to contact this phone number or they would be serving papers against me from my own county.

Computer message telling me something about this was my notification and a number of my case.  Had NO idea what it was about.

Found out that this is a legal department trying to find people.

What is the name of this "legal department" trying to find people?
