Checked online banking today and EDF have taken out a DD which is more than double what it usually is. We have received nothing in writing and I'm obviously going to give them a ring. I don't want to be fobbed off, so does anyone have any experience of what they are likely to say and what I should then say in order to get this sorted? It's made me so angry. I know we have probably used more electric over the winter months, but more than double? I don't think so!
