Agreed
I can report the following anomaly just encountered a couple of minutes ago:
I disbursed money out of my Alliant checking heading, owing to ACH initiated at Alliant, to Keesler.
The money arrived at Keesler same day and was credited to my Keesler account straightaway.
The money shows, on my Alliant transfer page history of past transfers, as having been disbursed timely, in accord with my instructions.
The money, according to my Alliant online checking account history, shows as remaining in my Alliant checking! The latter some twelve hours after supposedly having been sent to Keesler and actually arriving at Keesler!
Want an explanation? I have none, other than the explanation you already provided, above.
