Thanks all for your comments.
I made a telephonic purchase last night using my ATM debit card. The vendor is reputable.
The person who processed my order, though...entered my card number 11 times. No doubt he was attempting to get an "ok" or some other signal, but he wasn't patient with it.
Today, my account is frozen. My checking balance is zero on paper, and minus $1,200 or so in total. My savings account is intact and will cover, but it, too, is frozen...pending receipt of the sales transaction by the bank, who promises to release all funds not actually being paid when the receipt comes in.

Crap-ola.
I tried to sort things out telephonically and the bank agreed to rectify the situation via a telephone call from the vendor. The vendor agreed to call the bank and sort it out that there should only have been one transaction and not 11.
But that was at 11 a.m. It is now nearly six hours later...and nothing has changed.
