What do you do when advisors just don't reply?

Once again I’m a bit confused by your post, is this in anyway related to your previous posts about the app?

In that thread you state that you have a credit meter and pay monthly, 

Are you complaining that the meter reading used for when you moved in is wrong?
(You should always photograph the meter readings when moving in and when moving out, that;s your proof if there is any dispute later).

Or are you complaining again about the estimated usage?
Estimated usage will get corrected by supplying actual readings,

What did you complain to the Ombudsman about, and what was the ombudsman’s ruling?

Two things to consider:

Firstly the previous tenant’s moving out meter reading may be quite a bit lower then your moving in reading.
For instance if the landlord has had work dome on the property during the tenancy void, that work will have used electricity. There will also be daily standing charges building up.
(Of course the landlord should pay for any energy used and standing charges during any tenancy void, but not all landlords do).

Secondly even after you had the tenancy, if you were away from the flat the heating may still have been on using energy, and the daily standing charges still need to be paid.

Ovo had to install new smart meters. They scheduled a day of installation. I made the mistake of not photographing the reading the day I moved in. I accept that. What I don't accept is Ovo using an estimate for that first month that means I am paying higher than my average monthly consumption for a period I spent half the time even not moved in.

There were no white goods to consume electricity.

The boiler wasn't turned on for half the month until I moved in. So no heating or gas cooking.

The landlord didn't do anything between tenancies. There was no changes to the property. It's a cupboard of a flat.

There was no consumption for the period i hadnt yet moved in. Standing charge, sure. I am complaining about the estimated start reading for the beginning of the tenancy, which obviously led to such a high reading when they took the final reading of the previous meter. I am not in control of the estimate, that was Ovo, and despite providing evidence I wasn't there I was screwed.

The original bill before the final readings had been confirmed was even higher and included the previous tenant's bill. That's why I went to the Ombudsman, because the promises of it getting resolved lasted weeks then months.

The title of my comment is "What do you do when advisors dont reply". Because it seems that having tricked me to acceot an estimated figure without knowing what amount it will actually lead to, Ovo now refuse to address the injustice. Or is it standard practice to ignore emails? Frustrated. Researching cheaper companies, used to be with Octopus and never had this problem.

You say that you went to the Ombudsman, but you don't say what was the Ombudsman decision/ruling?

(You can still go to court, at your own cost, if you don't agree with the ombudsman decision. However be warned that the court will usually (nearly always) agree with the ombudsman decision).
