We have signed up for DD for all our supplies, but EDF did NOT activate the instructions for all our supplies, they missed some out. Because EDF has not activated the DD instructions, they charge each time 2 % extra for wrong payment method despite it was their own mistake! Although they were asked several times, for one of the supplies, the DD is still not activated after over 10 months! They promised last time back in May to get it sorted, but were unable to do so in further 3 months. EDF also usually ignores any submitted meter readings even the start meter reads of new contracts! For another supply EDF charged us Late Payment Interest for the days between payments for the invoices based on estimated and actual readings, although we were credit! EDF responds very slowly to sort any problems!
