I'm just curious about this. Last night I was doing some on line banking with PermTSB and noticed a direct debit had been deducted from my account but dated 15/3/2011 even though last night was clearly the 14/3/2011 and the DD isn't due until today, the 15th! So had I checked my account this morning, and not last night, all would look normal as the DD is dated for today even though it was deducted last night. Maybe I'm wrong about this but I always thought DDs were presented on the day they were due. Can anyone clarify the way it works?
