"Core Resolutions is a sub-division of Nations Recovery Center" Right from the page you are referring to. Now they say that National Recovery has never called anyone using the name Core Resolutions, but that is simply a play on words. They had people that work for Core Resolutions call. As I said, Georgia is the world's #2 capital for crooks pretending to be debt collectors, right behind western New York State. As I have also said, no moral or ethical person would take a job as a debt collector.
I had a missed call from this number. I called it back and the woman stated my name and I said yes. She asked me if the last 4 digits of my ssn were xxxx. I told her I'm not verifying any personal info over the phone. She got an attitude and stated that they will peruse the 4 allegations against me. Then hung up. The company name on the recording I believe is Core Resolutions or recovery. It's an Iowa number.
