Has anyone had this?
We have been paying £150 per month for electricity all year and there was a nice credit of £700 to see us through the winter.
Ovo emailed us today to say we have been under paying since 2016 due to a billing error and we now owe Ovo £350.
They said that they will refund the £350 as it was their error and as our 2-year deal has finished we need to renegotiate a new plan.
Has his happened to anyone? So much for smart meters.
