Capital Aquisitions & Management Company Unwilling to provide proof of debt rude and menacing Rockford Illinois

I received a call from CAMCO today, so I called back to see what this was in regards to, Debbie the woman that I spoke with said it was a debt from 1992 with Levitz that was never paid. When I asked if she could provide me with proof of this debt, she placed me on hold and that's when her attack dog Kathy got on the line and said that the account was too old to have any information on, but never the less I owed and I had to pay it ($3,000.00). She (Kathy) said that she had my credit report and that she did not mean to be rude but that I had alot of different names and had the audacity to ask me if they were aliases, then she said that the report indicated that I lived at these 2 addresses of which I've never lived at.

Anyway, to make a long story short, after arguing with me, the account was no longer with Levitz it was with Speigel, and she placed me on hold to call Speigel and that they said that 2 payments had been made on that account which made it a valid debt. I got so angry with her demeanor that I hung up and called Speigel myself, Kent the "gentleman" that I spoke with informed me that the account number this Kathy had given me was not a valid account. What can I do about this, I live in Los Angeles, who should I contact, any ideas are welcomed.
