They called me and I immediately got a recording that all their associates were busy but to please stay on the line for the next available associate.
If they want to talk to me, have someone on the line when I answer. I don't hold for incoming calls.

wow.  so they call me and all the caller id says is nco.  i get the stupidass recordind about waiting and then someone came on the line with a really weird voice and.  i couldnt understand what they said and they asked for someone i dont know.  so i tell them they have the wrong number and it tells me that all incoming and outgoing calls are monitored.  then it was silent so i hung up.  who are these people???

My caller ID from this number also said: NCO.  They ask for a person that doesn't live here.  When I told them that, they said that they'd remove my number and it would take up to 48 hours to do it.  I have a high suspicion that it's a collection agency.

They call our fax line every day 8:05AM (EST).  The caller ID shows up NCO.
