Payment taken out 1 day early

Hello,
I’ve been trying to resolve my past due balance since Sunday. My internet was suspended yesterday and I spoke with a customer service representative on the phone. I made an arrangement to pay the whole past due balance tomorrow, Dec. 10th but it was taken out in full today leaving me my account overdrawn and $200 in the hole due to other payment that were actually scheduled for today. Can anyone help me resolve this.
