Got a call, but did not and will not answer when this number calls.

As usual, I let it go to voice mail.  I received what sounded like part of a live voice message from a man with a thick accent (hispanic maybe?).  I caught "500" from him along with other voices in the background.  I read other postings about this number.  I have no debt, nor have I ordered from some of the companies mentioned.  It seems to be yet another mass calling.  I gave up reporting these a looooong time ago.

I am being harassed by this phone number.  They call repeatedly and there is no one on the other end speaking.  It is just silent.  I have tried calling back and there is no answer or anything, it just leads to a disconnect noise.  I am worried they are calling about a debt and not allowing me to respond just to keep it in collection status, what do I do?

I got two or three times call from 213-725-5371 I did not answer because I don't have this number in my contacts. When I called back latter they never answer.

I've been receiving calls from this number for weeks now. I finally answered today and the guy said he was from ASDF national debt services and could lower my debt. He already had all of my information, ie: name and address, but as soon as I heard this I just hung up.
