Man this sucks. I woke up on Sunday to get 2 emails from BoA telling me both my personal and business checking accounts were being closed. I’m not even sure why. My business checking account has zero activity the past year so it can’t be that. My personal checking hasn’t had any funny business at all. The last time I did stuff on it was sending Zelle and transfering money to people back in late April. The only recent activity in the account were 3 Zelle payments in early June for a total of about $2200. It’s just very odd. UNLESS the checking accounts were closed due to the cc side, of which one cc closed with a -$9K balance due to an accidental overpayment. That or MC did some internal chargebacks from charges in December that I had no control of. So I don’t know.
Lesson learned – if it was actually due to the Zelle payments, the old adage – don’t shit where you eat always applies here.

was the overpayment via debit card?
but also, don’t use zelle, ever. I actively avoid it. too many bad stories over the years all related to zelle.
So an accidental $9,000 overpayment sounds like you pad them twice during a cycle instead of letting autopay work. Maybe that was due to a cycling pattern?
I am wondering if just having a high negative balance would really trigger them if it was a simple extra payment accident.
