Who called from 5019753369

I called it. Its bill collector.. Collections. For what, not sure. I just got the word collections.

They keep calling.  Leaves no voicemail.  When I answer it is just real loud noise/ music on the line

Called tonight, after I said hello I got silence and then music.  On caller ID it said INTERNATIONAL C

Calls and just hangs up after saying hello

Keeps calling asking for spouse.  Refuses to give name of company unless given vital info which i refuse to do to unknown parties.  Said it was regarding a collections matter.  Told her to mail it because we want in writing.  Gotta be a scam!!!! Don't give them info.
