No message left, called back could not understand the person as he mumbled. . . . .

This number calls my phone about 3 times daily and leaves no message.  When I call it back an operated answering machine says press 1 for english so I do and then someone answers and says "This is "John" or "Steve" or "Jane" how can I help you?"  No company name or anything to let you know who it is that's calling.

I'm pretty sure its J.C. Christiansen (debt collector) trying to mask their 800 number.

Hi guys.. Got the same call too. Its a debt collector for businesses around Northern Minnesota. The debt this collector was calling me about is for a hospital bill but they provide services for other businesses as well. Hope this helps!

JC Christensen debt collector also calls come in from another number as well a cell phone number  in Madison WI 608-338-1918  they don't leave a msg but when I call back they answer as JC Christensen
