Most posts imply the call was fraudulent (not truly from your power company). I don't think so myself, but we don't know. In your post #13 you said you called some automated system at the bank and it indicated no withdrawal has been made (for October) and in another post you checked the power company website and it showed past due. . . but if the withdrawal was scheduled for a non-banking date between 10/11 and 10/13, then it will not post to your account until the close of business 10/14.
Anytime I have an issue like this to deal with, it's all I think about, but in this case, there is little choice except to see what the bank tells you tomorrow.
