I had the misfortune to switch to these energy 'middle men' clowns some two and a half years ago and based upon my recent experience of their, so called, customer care, I most certainly will not be staying with them.
Initially when I joined them, all appeared to be fine but within the past six months or so, things have gone from bad to simply dreadful with customer service, billing and attitude of staff at best described as appalling.
I pay for my energy usage by monthly direct debit and, by choice, I never allow my account to drift into debit with meter readings sent religiously on the 15th day of each month. Unfortunately, this is not enough to satisfy this company.
I am constantly bombarded with requests to book installation of a smart meter (although I have informed them on numerous occasions that I do not want or need one). I am seriously concerned with the unnecessary complexity of their billing together with constant increases in the cost of daily supply charges and now, without any explanation, they have taken payment from from my account for what they say, are discrepancies relating to estimated billing from two and a half years ago when I joined them. Even though all bills from day one are based on actual meter readings.
Attempting to speak to anyone at Ovo with common sense is virtually impossible, they are even in denial over the email sent to me charging my account for supposed estimated billing.
I have no idea why this company's practices have not been thoroughly investigated by the energy watchdog, they most certainly need to be, and with haste.
