Economy 7 Tariff Prices

Hi there, 

We recently moved into a new flat, and when we arrived we were told by the landlord that the house had been setup for Economy 7, though I had already signed us up to a 1 Year Fixed tariff with OVO. After a few phone calls, we have apparently been switched to Economy 7, but nothing shows up either on the smart meter or the outside meter so I have no idea what is happening - the immersion heater is also not working as expected, with the ‘7 hour’ switch heating the whole tank constantly. 

My main question though is that after asking to switch to an Economy 7 tariff, we’re not on a tariff that has a peak rate of 31.75p/kWh, and an off peak rate of 21.37p/kWh, as well as a standing charge of 62p a day - having looked around a bit this seems ridiculously high to me so I wanted to see if anyone else felt the same? I didn’t get any heads up about what this rate would be so I’m a little shocked and confused.
