I have an account that was with a credit card company, which sent it to their Recovery Service department, which then sold it to a Collection Agency. So the same account is showing up on my reports for each of those three Creditors, giving me three negative listings for this account. If I want to dispute the information and have it removed, do I have to do so with all Three sources? (OC/OC collection dept./CA)? If the CA agrees to remove it, will the other two follow suit, or vice versa?
