The bank has lost €15,000 in the mix-up and it is doubtful it will get much, if any, of it back.
The spokesperson admitted that while they know exactly who withdrew the extra cash, it is illegal to debit their account by that amount.
Instead, the bank is depending on the honesty of its customers.
It has written to them telling them it may be appropriate to return the cash, but that they are not compelled to do so.
However a bank official said yesterday that they were surprised that, so far, not one customer has been in touch to report they got too much. [My emphasis]
