Unfortunately, there is no option for zero stars. I have had to get the Ombudsman involved, twice, and I have now requested a subject access request for all information they hold on me, including audio as they record all of their calls. So make sure you get the name of the person you are speaking with, record the time and date, and ask for evidence of an email confirming what you have discussed. They have one month to provide all of the information. They say one thing on the phone, then send demands the next day which negates everything they have agreed with you.! I have had problems for over one year with OVO making up numbers when photographic evidence proves the correct meter reading. Interestingly, they had the wrong phone number, wrong email and also kept sending me the previous owners bills, without putting a name on the envelope or letter, only an account number, which suggests they were trying to con me into paying for the previous owners bill, which they clearly haven't paid. " a simple mistake" - no its not, not when you cannot log into your account and register your details. They wanted to charge £2,700 when i was only in the property for 3 days, had no appliances but still they insisted they were right, then told me it had increased to £4,000 in the same phone call! . . I refused to pay. I refused their "offer" of having a direct debit, no chance, ask that you pay monthly, do not let them take money from your account as it will be a nightmare to get that money refunded to you. I would suggest you cancel your direct debit, so they have to prove from meter readings and how much they charge per KW and gas unit, so you can be sure you are only paying for what you use. Yesterday I paid my final bill as i have switched providers, and I informed them that I would stop the payment if they didn't send an email confirming it was the final payment, which they did. Today I receive a bill for over £1, 200. which I am refusing to pay. They create stress and anxiety, and only want to help when you show them you have copied in the Ombudsman and will take it further. Interestingly they only want to "help" and phone you when they want/demand immediate payment. They are also unable to manage GDPR, as they ask you to confirm your name address and date of birth, when demanding payment, well, my answer was "NO, you phoned me, if you dont know who you are speaking with, well dont bother calling! and if it is for payment, why do you need to know who is paying the bill?" Banks tell us to be sure who we are talking to, but they disregard this by phoning on an unidentifiable number. They also need to switch you to an automated card payment, that is confidential, but they dont seem to, so you have no way of knowing if they are actually recording your card details. This company is a shambles, chaotic, and insincere. 3 hour phone call, only to be told to phone back in 14 days and re submit the reading as they didn't believe me! Well, no I was not willing to do that. I had sent them a photo, which has the date and time on, but still they couldn't manage this. DO NOT USE THIS COMPANY IF YOU WANT TO MAINTAIN A POSITIVE MENTAL HEALTH. Do yourself a big favour and swap providers, they may claim to be a cheaper option, but how does that work when they seem to make it all up as they go along? they claim to care about their customers, even spending millions of pounds, probably, on radio adverts - trying to drum up more business as i expect they have people leaving in droves. They are using your hard earned money to flaunt themselves even stating that they really care about helping people to reduce their bills - well , once I had stopped laughing, I realised how seriously dreadful they are, when you can keep your heating off, eat salad and still be charged hundred/thousands of pounds. This company seriously needs to be audited and investigated for fraud.
