I signed up for one of the Octopus tariffs where they control your inverter to charge the battery / go to grid at the best times. I've come off the tariff but my inverter won't let me change settings and give me a message "Settings for this inverter are locked and controlled by Octopus". I've asked Octopus 3 times to unlock it and they said they're relinquished it and it's an issue with the inverter. GivEnergy just straight up won't reply to anything I send them - any help at all or ideas would be much appreciated 🙁
