Applied for UA Business signature card using targeted offer. Declined the next day because "Business credit report shows bankruptcy"

My business is essentially a side gig which never had any bankruptcies or even a credit history AFAIK.

I have a business ink cash card (downgraded from ink plus years ago) with a substantial points balance, and it remains open.

Question is, should I bother calling the recon line? Or would it be a waste of time, or even do more harm than good?
