Can anyone explain to me why OVO, rather than applying adjustments to the current billing period, quietly make adjustments to historical bills (and hence every following bill) without so much as offering a single word of explanation?
For example, my bill for the period 14th Mar - 13th Apr 2023 has, to my certain knowledge, now changed at least three times since being issued. I have four different copies downloaded on the 22nd April, 11th May, 7th August and today and they all show different charges and closing balances. OVO have never communicated to inform me that previously issued bills were incorrect
At some point in the last week, despite there being no new credit transactions my account, I have suddenly gained more than £50 worth of credit that wasn't there before and I then noticed that the charges and closing balances on every single bill back to February (as far back as I have checked) have been changed in the last week and that the credit is an accumulation of these unexplained changes to previous bills.
Bills are a formal communication. It is quite simply illegal to change them without communicating with the customer to withdraw the previous bill and inform them that a new one has been issued. If, for example the adjustments had resulted increased debit balances, the failure to communicate the change to the customer would result in an unenforceable debt.
With SSE, for example, if they changed a historical bill, they informed the customer and you could see both the original and amended version of the bill in the billing history – with OVO there just seems to be a deliberate attempt to gaslight the customer by silently making the changes in the hope that the customer doesn't notice and, like most customers, hasn't bothered to download copies of their bills, and assumes that they themselves have made a mistake.
