DEBIT ORDER

I'm so very upset right now I cant even describe it. We had an agreement that they will debit a combined amount for all my policies in one, Today they come and debit what they felt like debiting. When I phoned in to query this I was told by the consultant that they debited so because its DECEMBER, really? And he even insulted me by asking if I have enough money for the other remain policies to go through. Who give them the right to go in and out of my bank account because its DECEMBER. When I asked to speak to a manager/team leader/supervisor/2IC I was again told by this consultant that there is no management because its DECEMBER. This is the worst pathetic service ever. I have NEVER received any sort of communication from them stating that because its DECEMBER they will debit halves and halves of my policies' contributions. And the consultant goes on saying that MAYBE they will again debit today or after the holidays.... Really??? I need this sorted out today
