I have pay as you go meters. Last month I put £30.00 credit on for my electric. The money was taken out of my bank and I got a message saying my top up had been unsuccessful and my money would be refunded. Tried again with £20.00 and it went through. It took them 3 weeks to refund the money. I am beyond fuming today. Put £30.00 in, they took the money and said the same thing as last time. Put a further £20.00 on they said again that the transaction had been unsuccessful and they would refund the money. £50.00 down no electric and can’t speak to anyone because they don’t work on Sundays. Changing suppliers ASAP!!!
