CBCS Is this company even legit? Columbus Ohio

From what I've read, many others have received a phone call similar to the one I just received. Not only was the woman ignorant, but she couldn't even get the information correct! She said she was trying to collect on a PECO bill from Nov 2005 for an address where I had moved away from in Aug 2005. Then she would switch the year to 2004 (if I hadn't paid a bill in 2004, there's no way PECO would've continued to provide service to me through August '05). I still don't know to which year she was actually trying to refer!

Then she said I need 3 pieces of mail from 2005 (2004) - sure, I keep mail laying around for years, 2 copies of personal ID with my picture & my social security number. Are they nuts? Sure, let me just throw all of that personal information in the mail right now for you! I don't think so. She said I have 45 days to take care of this. And I'm just hearing about this now, in Feb '09? Something just doesn't sound right. She also said I needed a police report if I'm saying that I didn't live there.

This is crazy, but I don't know which course of action to take - certainly don't want my credit to be affected, but are these calls even legitimate? What is everyone else doing? Help, please!
