I have lerked the boards for some time and I have done a little credit cleanup thanks to this board. I have two very old(5yr+) CO credit lines. I have in the past received collection letters from various CAs, non of which appear on my credit report. The only lines are from the OC showing CO and no lines for collection. Where should I focus? On the OC since they are on my CR? Or do I need to deal with whatever CA flavor of the month they are using?
