Since the "Smart meter's" have been fitted we had nothing but trouble, we have not been credited our balance from the old meters as promised, the website does not work, the app is impossible and you are left without a viable way of topping up your account and left ultimately without gas and electric. The customer service is void and you just get passed to other departments and other advisors where they "look" into your complaint then fill you with empty promises, or you just ignore you. The facebook page is filled with complaint's and the advisors on their social media sites are pretty arrogant or continue to ask irrelevant questions without actually reading the complaint's. I have lived in many third world countries and received better service than this 'British Corporate" company that seems to be stuck in the dark ages where customer service and competence is concerned. We are now stuck with this poor excuse for an energy company as the more competent companies do not take on client's with these dreadful "Smart meters" I just hope this helps others whom are thinking of switching to the smart meters. Switch provider while you still can don't be left without energy like we constantly are!
