What should I do if my bank letter is 7 days old before renewing my Non-Immigrant O Long Stay visa in Thailand?

Hi. I have a quick question at the end of this, but thought I'd share a quick message from my trip to Immigration yesterday (Friday) to renew my Non Immigrant O Long Stay visa (retirement visa). I've done this twice before, successfully, but ran into a wall yesterday. Thought I had everything I needed, you know the list. I got the bank letter from Bangkok Bank, Silom, the day before (Thursday) and asked them to update my bank book. That turned out to be the problem. I hadn't updated it since last May, and at the bank they only included transactions from Feb 2021 to now. Seeing the three new pages of updates, I didn't really check the dates. I "assumed" the bank book now had all of them since the last time I did an update. Yes, everything else was in order but because the bank book had "a gap" with no printed transactions from May 1, 2020 to the end of January 2021, I was denied (even though my balance has never fallen below the 800k requirement). I tried downstairs to get a full-year print out but, unlike many other banks who will do this the same day, Bangkok Bank said it would take 3-5 working days. My visa is up on May 4th. May 3 and 4 are bank holidays. Time is not on my side. I screamed on the motorbike back to the Silom branch and basically wouldn't leave until they agreed to try and get me a printout (after many times of "I'm sorry sir, can not").. Anyways, I got the print out at about 5pm. So, remember that, regardless of any other statements, ATM receipts the same day, etc,, it seems we need ALL the transactions of the last year as part of what we submit. Now my question: I will return to Chaeng Watana on Wednesday morning, one day late but the immigration lady said no late fee because of the holiday closure. But now my bank letter will be exactly 7 days old. I've read its good for 3 days, 7 days, 2 days, 4 days. Any idea? And if I need another one, does anyone know if the Bangkok Bank downstairs at Chaeng Watana will issue one? I could go to Silom branch before i go to immigration but it would be cutting it close as I really need to be back to downtown by 2pm.

Whatcha think? And thanks for listening : )
