Part of the problem is a bank training you on recognizing that they have countless silly obscure rules for their own purposes - for example in what your password may be and how messages to their employees might be (mine limits the messages to be very short - no space to explain anything.) So you are quickly trained to make do with the silly rules. I.E. multiple ACH over several days and move on with your life... Or in the case of messages, I just continue my explanation in multiple messages.
Either way, the bank has trained the customer to work around limits. They can't have it both ways.
