If I could give 0 stars I would. I pay my duel gas and electric by monthly direct debit and usually receive a bill every 3 months. We had not had a bill since November so queried this, to be told oh sorry, we have de-energised your electricity meter but they don't know why! We have still been receiving electric and our account is over 1k in credit. I have an open complaint with them but just keep being told each week they need yet another 7 working days for their specialist team to look into it. It has been 3 weeks now so far and still no bill or answer as to why they de-energised our meter and didn't tell us either. Will be looking to move to a different provider if this isn't resolved quickly.
