To start with, I have been transferred without been asked from Spark Energy to SSE. Since everything would remained the same, i was keen to give a chance and see how it goes. All good, till i asked for a refund of the positive 600£ balance which i am entitled and paid for. Since then, they have put me into a labyrinth of asking again and again foto of the readings and then finding any excuse not to refund the money 2,5 months now, I've never had such an experience with any other company and it's safe to say that they are playing with people's honest money. I've never seen a delay when they take the 100£ every month but when it comes to a rightful refund they drive you into a faceless labyrinth with emails hiding. Shame.
