got calls

I work at an answering service.  Guy from this number calls for person we've never heard of.  Refuses to leave company name.  Tries to sound all official but ends up sounding more officious.  Keeps trying to give me MY legal rights on whatever the hell he's talking about.  Sounds like some sort of collections BS to me.

Demanded my daughter's address, stated he had a summons to serve her and would deliver it at work if he wasn't given it. Wouldn't identify himself or company. Very demanding and rude.
