I don't know how they get all these five star reviews? Customer service is dire. They took 10 months (with all sorts of excuses and ghosting along the way) to upgrade our meter to enable us to get on our chosen tariff. Then they said we still couldn't switch because we had the wrong type of meter. Now they say we can't switch because our account is in debt. We have a variable direct debit set up so they decide how much is taken from our account and when, not us! We made an extra payment last week of the amount they said we were in debit and tried to switch again, but now they are saying we can't because we are in debit again. There's no new bill on our account so who knows where they get that idea from. They offered us compensation for their terrible service but they haven't paid it. When I raised an official complaint they chose the same guy who had been letting us down for months to resolve it, rather than escalating it to someone more senior. What a shower.
