Spiteful and evil company. They charge a very high directly debit and you can not lower the amount even when you are in credit of £200 or more. They must have some cunning ways as I am paying less with Octopus even the unit price and daily charger are higher. When I left OVO, I had credit so they refunded me £61.26 but they refunded me twice. It took them a while to admit the error as they kept saying I had outstanding bill when I never cancelled direct debit. The amount changed to £59.04 without any explanation and they even got debt collection company involved (Oriel) for a debt which was due to their error. Paid Ovo directly £59.04 but Oriel demanded £20 more. A bag of crooks.
