Any help is appreciated History: CA reporting three different TL's. Disputed all three, one dropped straight away, the other two were verified (figure that one out) After the CRA verified, sent validation letters for the remaining two. Today, (what appears to be) a duplicate of one of the accounts that were verified shows up with same OC, same open date, different account number, slightly different amount. Should I dispute this as a duplicate or send validation first, then dispute?
