3 calls in 2 days-returned call they are robo dialing and fishing for 3rd party companies!  This call was for a company called LC Carpeting!

It's an IRS trying to get a hold of you. I got this today and called them back, talked to their tax representative about my account.

CALLS EARLY AT 8:03 AM ON 8/7/12 LOOKING FOR SOMEONE NOT LIVING HERE.I DO NOT ANSWER THESE CALLS AND THEY LEFT A MESSAGE. LEFT HER NAME AS CARRIE SMITH. A PEST FOR SURE.

Receive daily calls from this number.  Recorded msg goes something like -- "I have been trying to contact you for several days.  This is not a solicitation call.  I have important information for you.  Please call me back at 877-3018509.  I decided to dial back this day and the recorded answer said that this call may be recorded for training and compliance purposes.  Please hold for the next available representative.  Subsequently, I heard ringing which lasted at least 2 min. before I finally hung up.  Thought this was against the law??  My caller id says EOC Services.

It's a collections agency in MA.

they are another  collection agencies filled with low life people (who can't find job )

I've had the same issue that all you have mentioned. Before you take out your check book.  Research these people, most of the times they call is just to get us to write a check.  I ask him to give me the address where to make payment and I was told that I should give them the routing and and account number to make it easier for me.  Yea right.  BE AWARE EVERYONE!!!!

I am one of those people who knows who I owe and what amount I owe.  Don't be an idiot people.  You are smarter than these people.

Found the number on my caller id.

Mr. Douglas leaves a message saying he is calling from "EOSCCA, on a time-sensitive matter" and asking to "please return his call," quoting this number "877-301-8509, at extension 3035" with some reference number.

Calls repeatedly; recording

If anyone knows WHO this number belongs to (877-301-8509) please post it. I am (#@$*%#@) sik and tired of them calling!

calls my New phone number all the time

This number has been calling my cell phone.  I called back and find this phone number is a debt collection agency.  They were calling for somebody, which I have no knowledge of.  They agree to remove my number from their records - we'll see if this takes place.  
I've received a few of these calls with the same voice message.  I tried calling back a couple of times, but got cut off.  This last time I spoke with a human to resolve the calling issue
