The Bank Job, part 2

Today is a national holiday–meaning no banks are open–but I received a personal followup message from Bank of Montreal. Unfortunately it was informing me that the inquiry we have received from you was blank. I’m not sure exactly what that means–mail doesn’t just go blank–but I resent my original message with their tracking number attached. I suspect their mail server erroneously tossed the entire message because of its suspicious attachment: my S/MIME signature.

Still no response from the virtual banks.

[Updated late afternoon: Got another similar response from BMO. I’ve replied once more, this time sans signature… if it doesn’t work this time, BMO’s off the list.]
