Called saying they were delivering documents and needed a time to deliver them? Probably a debt collector or other scourge of the earth?

I just got this new number on Saturday & this is my first unknown caller. didn't answer.

This "john smith" called and started getting aggressive while I was simply asking why am I getting papers??? Rude [***] guy

They called looking for our son who has never lived at this address. They also stated that their currier would be delivering documents next week and needed to make arrangements to do that. The lady asked if I could get him a message ,I told her I didn't know to which she quickly hung up .I wasn't surprised to see that they are a collection agency ! Beware..

Called to confirm a delivery in the middle of the worn day. Said they had legal documents and would need me to sign for them and provide ID. Sorry I've been served court papers before and yes you have to sign but you don't have to give ID and its delivered by sheriff or constable not an out of town delivery service.
