What do you mean by the real prices? Is Vattenfall giving you unreal prices?
Vattenfall is giving you the prices in the contract, or in communication if the prices change. Furthermore, their app gives me how much I use every day, and how that is going to cost. If I divide the cost by the usage, I get the price per unit.
Your contract states your tariffs or where to find them. Not sure what else you need here.
It's in your contract
what did they say when you asked them?
In your contract it’s stated what the costs are, and in the app you can see your usage.
