This is for Commonwealth Financial Systems, a division of NCC. This particular call center is in Kentucky, but principal offices are in Pennsylvania. I called them back, they ARE a debt collector, and the debt they were calling about was legitimate. I was able to settle for half the balance. They were very polite (probably because I was able to pay up!).
Before I paid them, I looked them up on bbb.org (the Better Business Bureau). They are not registered with the BBB, but there was enough information for the BBB to verify that they are a legitimate business. They have a "B" rating (out of A+ through F), mainly due to complaints. They had, I think, 149 registered complaints.
Hope this helps.
