This is a collection agency called MCI.  Just for anyone's information

In the voicemail they left me I couldnt understand the person's name and they didnt leave an explanation for why they called.  When I called back and asked what they do, I was told they work on "projects." When I asked what kind, she refused to tell me until I gave her my phone number and first and last name.  I hung up after that.

Actually, this seems to be a collection agency.  They are called New Concepts International (NCI, not MCI) and they are definitely based out of Concord, NC.  I too had some trouble understanding their voicemails and they sure don't leave any sort of information in those messages.

I just called and its not really an (collection),collection acency. They was calling for Duke Power. Duke Power gives it to them to see if they can collect money in a few weeks and if they cant then Duke takes it back and gives it to the An Acency that gets nasty I guess. Before they charge it off. They only except $100 payments Not less than 100 bucks at a time . But you can pay Duke less by phone or by person. And then let them know you paid something with comfirmation number. And they can keep it before Duke takes it back. The guy I talk to was very nice. Even when I said I have no money at the moment. I told him it would a couple of weeks before I can do anything. But there was no garentee how long they would have my account.

Same here, they were calling for someone else I knew but they always refused to provide me with more details about the reason of the calls. The only thing I got from them was the name of the company: "New Concepts Financial Group."
