Seems you did fairly well getting a 40 % payout.
When the letter arrives be sure it states what you asked for and is infact from Capitol One on their letterhead and signed by someone of authority there.
Make payments only to them directly and keep receipts.
Insist credit bureau file be updated Immeadiatley after payment recieved else it could take months.
Question I have is if TRC said they now own debt....what has Capitol One got to do with anything at this point.
