They called asked for me by my first and last name and said they have pappers scheduled that they need to deliver

Did they ever show? They asked me if I would be home between certain times but didn't verify my address.

Real process servers don't warn you they're coming because then you could avoid them. This is a scam to try to scare you into paying them not to "serve" you.

deliver something that doesn't exist, but they can panic you enough to pay them extortion money. Learn what you should already know about debt collection at the CFPB web site and your state attorney general's web site. While there make sure you report these crooks as well.
