My real fear here is that revenue from last year was fabricated. We know this year was minimal so can't be affected too much, but last year...that could be the problem. So the receivables balance at 31/12 could be written off if it's not actually there.
Seems strange that once new managment turned up revenue went to zero. Could be COVID, floods etc. Dunno, just in a bit of a funk now worrying about this stuff. Very disappointed.
