It's a little hard to read it all bunched together like that lol. Did you dispute?
Just so you know, when you dispute an OC account, certain aspects of that account are removed from scoring, like the CL, balance and payment history. When the dispute is resolved your score will either go back to pre-dispute score or up or down depending on what they do with the account.
If you owe it, yes pay it.
No, your score will not go back up until the dispute is resolved.
