*******ly taking early payment of debit order

My debit order is due on the 25th of the month. Auto and General decided in December that they would put through the debit order on the 23rd of the month. This is ******* as they are taking money before it is due. My funds were in my bank on the 24th but because the debit order went through on the 23rd I am now being charged a fee of R115,00 by my bank. I believe Auto and General and any other company that puts through debit orders early are acting **********ly.
