Something changed after I replied.
An earlier contribution should not silently become a confirmation of new details.
Do not assume the earlier act carries over.
Changed receiving instructions can affect a previous review. The office needs to know which instruction your contribution concerned.
Use the established office route.
Tell the office what changed without entering account details or private files in this website. The office determines the next supported contribution.
Keep the history clear.
The earlier submission remains history. A replacement needs its own accurate account and any review required by the office.
