Who called from 3086333077

My husband keeps getting a call from this number and they don't leave message. No clue who it is.

This comes back to a collection agency.  ARS Inc.  from
Scottsbluff Nebraska and many other locations.

Pain in the [***] [***].

Calls ALL hours everyday, won't tell me where they are or who I owe but I "HAVE" to send $950 to avoid fees..

Calls at least twice a month says I still owe $400 but won't give me an address to send a check. I've got one envelope in the mail at the start of the year (2017) that said scottsbluff NE on it and saying the same thing the woman told me but no return address. I only make roughly $300 a paycheck so I can't afford sending $400 to just anywhere
