Bank of America Bank account or service department,

Checking account Problems caused by my funds being low Missouri

I paid my - - credit card bill online through - - 's website after - cst on -/-/--17. When I checked my checking account through bank of america the next morning, I showed a transaction processing on -/-/--17 for the payment I made after -. I am not sure why this payment was processed after - on the same business day when I did not pay with a debit card, I paid per my checking account. I have never had a transaction paid through someones website process the same day. This is not possible.
