Cach

I've had a cc in Collection with CACH for a little over two years now, first it was with Cambece (one of CACH attorneys) and then it went to Lowry (another CACH attorney), it has always been on my credit report at CACH or Collect America I can't remember for sure which one, but now it has disappeared completely from my creditor report (Experian and TranUnion). I'm not exactly sure when it actually went off, but I can access the reports that I have pulled for the past month, and its not there. I figure it has been sold to another CA. I was just wondering if anyone knew, if there is a certain CA that CACH seems to sell off to?
