Aargon Agency Made two entries in my credit report for unknown debt ($70 each!) from 5 years ago Las Vegas, Nevada

Perfect credit, never missed a payment, and up pops two entries for a whopping $70 each from something that I was never contacted about and had no idea that I owed.  When I called, they didn't seem to know much more than it was a hospital visit from early 2007 - the entries were made in June 2011.  No bill, no idea, yet Experian and Transunion just allow some fly-by-night company to make two obviously erroneous entries into a perfect credit report.

This company is obviously crap to do something like this.  But I want to know how the h**l Experian and Transunion don't have some sort of filter to catch BS like this.  It's a time waster.  I called and paid immediately because of the low $$$ amount - likely bogus and completely made up.

Is Aargon Agency a fraudulent entity?  Do they steal identity information, freely available, and make up charges?  Or is this a real company?  I'm seriously asking this... as I don't know whether to call the FBI or what.
