Is it possible now to have been announced from the platform as "no longer a jw" (disassociated) and not know it? (no letter or call).
It was common practice on occasion ie a JW compromising on neutrality to simply verbally "spread the word" that so-and-so should be treated as DF'd. They did not want to DF someone for joining the military or voting as that could be construed very negatively by some Governments. So, for the record, said person was simply choosing not to associate but never had any official position taken against them.
