They stated to have the bank statements showing everything was paid but the company refused to look at it. Sounds like they may not have been in a deficit but company refused to look at anything
Personally, if I knew they were gonna shut me down if I didn't pay before X date, I'd fight it up until X-2 days, pay it, then continue fighting (depends on the amount of). But it's not clear that OP was given such a deadline.
