Appalling from day 1, overcharging on electric (4.5x my usage - £193 a month!!!) undercharging on gas. Might get a statement in two weeks of maybe 4 months but never consistent. Contact centre team fail to follow up on actions like generating statements and offsetting credit on one account to the other. 2 months to get final bill and still awaiting refund even though I was told it was arranged. Followed their customer complaint procedure in September and still waiting to hear back... now they won’t speak to me because of complaint with Ofgem they see that as “not being willing to speak to them anymore”! Left them in September because of the poor service all round!!! Avoid at all costs!!!
