Several excellent replies. Agree with calling and asking (groveling, begging, whatever it takes). All issuers are MUCH more likely to waive/refund/credit late fees than finance charges.

I’m very rarely in the same situation. Last time was due to having opened 2 identical Citi Hilton cards within a few days 8 or 10 years ago and confusing statement and due dates. Saw a pricy late fee and finance charges. Called Citi, pleaded my case, had all fees and charges waived and refunded/credited back. It is possible.
