That's ok. lol I was looking through previous posts to make sure I hadn't misunderstood and told you to send a GW letter to a CA!!
If those are all paid, then yes......go ahead and dispute them first. Look carefully for any inaccuracies. If you can't find any, then dispute as "no knowledge or records of this acct".
See if any of them drop off that way.......and then if not.......then you can try going directly to the CA.
