received didn't answer - message said some thing to the effect of documents with unsatisfactory account and gave me a 888 number to call back with account number - blocked now

I received a phone call from this number.  They are a scam debt collection company called Impact Mediation, claiming that I owed a debt and that they would move on filing court precedings if I didn't pay.  It's all a crock of [***].  I filed a complaint with the Consumer Financial Protection Bureau hoping that they'll stop calling.  I'm blocking this number for now.

See note above

Usually, when these type maroons call and leave a ridiculous message, I block them immediately. This one slipped by me the first time.
Again "unsatisfactory documents", "grievance", etc.
Call 877-680-0046

These low life scum of the earth people need to get a job. They are trying to scam people so they can do more evil in the world.  Don't answer and don't give them any information.  Report them to FTC, FBI and any other government agency you can. They don't even have any debt they bought from someone.  It's all a LIE !!!!!!!!!!!
