Request to change debit order date

Last month or so I called Customer Service and asked the consultant to change my debit order date from 25th to the 1st. I told her I could not change it myself as it was greyed out. She assured me that she changed it and will monitor the change that was made, but till today it is still not changed to the 1st. Last time I had to pay a penalty fee because of a debit order that went off before my salary was even paid in.<br> <br> I'm affraid this **** must come to a stop. I refuse to pay any penalties and if this goes on I will cancel my contract and not pay you a cent.
