Is it a scam

I got a message yesterday on my phone from a Joseph, and he just said he had been contracted to deliver documents to me today between 3 and 5 and if i was not there he would come to my place of employment with security and my supervisor. I would have to have a photo id to sign etc. It also said there was a filing party and gave a number but it didn't say who the filing party was. Pretty sure it's a scare tactic. Also think it's in some violation of the Federal debt act. Thanks. (they also just called again this morning)
