How to get Genbank to update wrong annotations?

I am writing regular error reports for plant sequences that are being annotated as fungi and vice versa to the GenBank email adress for annotation updates. About 3/4 of my email are being ignored and the wrong sequences are still online, although it is obvious they are not correctly annotated.
I think this is highy concerning.
How can I get GenBank to listen to me? I put a lot of work into trying to fix all the errors I can find.
