Avoid them unless you love being sent bills of differing amounts several times a month . Ring them to set up direct debit to be told you need to pay 300 a month for a one bed flat . I'm on economy 7 and realised tonight that they have been charging me the day time higher rate at night as well . Dreading having to spend most of tomorrow on the phone to them . Tried switching but they blocked it saying I need to pay them 94.00 first, I think the boot will be on the other foot !! I've registered in their priority register as I'm a pensioner , but when talking to them today, they told me they don't give any help to anyone- vulnerable or not - they actually suggested I move supplier but then blocked it . I give up .
