So can the electric company do something at their end and give him some credit for electricity?

Hello all, A friend of mine was on the phone to me yesterday in tears, his benefit has been sanctioned, and he will not be paid any money until the 15th May. His Pre-Payment electric meter went off yesterday after he exceeded his credit and is now sitting in the dark with no heating. He has been told he cannot apply for a crisis loan as they have now gone and the council do not give money out. He has no food, no electricity, no heating and no credit on his phone now. I live 200 miles away and cannot get to him. The DWP are adamant that he is to get no money and the Citizens Advice helpline is constantly engaged. Its cruel what they have done to him. I have advised him to goto the CAB office first thing. What can he do to get Electric, heating and some food. (I thought about food banks) Any tips please.... till I can get him some money after I get my benefits on Wednesday. Thx Peter
