Not just the worst energy company to deal with, but the worst company to deal with EVER. Absolute shambles of a company. Billed for an outstanding balance ten months after I left, after numerous conversations with chat bots and/or overseas call centres I finally managed to agree a payment plan. Three times now they haven't collected the first payment, then write to me chasing the money. Contact them again, explain the payment plan agreed, they agree to collect. Don't collect the first payment, and it starts all over again. Would rather revert to living in a cave with a campfire than having to use these jokers again.
