Actually,  it's not a scam agency,  they are legit debt collectors (that's sort of an oxymoron) .  If they have the wrong number,  just tell them and they will quit calling you.  That worked for my situation.   If you have a debt owed,  or feel like you paid it,  then good luck!

Get a call from this number who shows they are IC System.  I never answer from a number I do not recognize so I don't know the nature of the call.  This is not the only number that I get with the same results.  My number is listed with donotcall.

Called me 3-20-17 @ 4:21PM
Asked for me, but with weird calls coming in lately I  asked them who they were and what they needed to talk to me for and they said it's confidential information. I told them withoutme knowing what information I need to relay I'm not going to waste my time and look for her and they hung up

Called twice in the past week...rimgs, no message

Oh no. Don't say yes. I've heard of a new scam where they ask your name, you say yes, then they can authenticate you somewhere else. Be on the lookout for any new crap that pop up. Good luck.
