Debit Order Triggered Early

The debit order on my account for my policy went of on the 24 of the Month and not on the 27th as agreed in the policy agreement. I understand that there was a public holiday on the 27th, however, companies generally pay on a stipulated date and not before despite there being a public holiday or not. <br> <br> As a result, the payment was returned as unpaid, and I incurred charges for the default payment. In future, if there is going to be instances like these please rather push forward the debit order to after the said date and not before
