"If i could leave zero stars i would certainly do so. Economy energy have owed me approximately £110 since early November 2018 when i moved to Eon. Three phone calls later to them and 3 lies from them about receiving the refund and i am still waiting for the money . Please stay well away from this company if you want ever to receive any credit back on your final bill. And as the other reviewers have noted the customer service is dreadful."
