I was switched to Octopus when my utility company went bust. They seemed ok until I noticed a few things on my bills. I always provide meter readings when prompted, every month and submit them within the 3 day deadline given. On 2 separate months I could see that I had been charged for half a meter read bill and the other half as an estimated bill. In all my years I have never seen this so I queried it and was first told that I need to submit meter readings which is why it was an estimate, which I went back to say I had (I had the reply emails thanking me for submitting them). Then they said it was because in the middle of the month price increases had occurred and as I hadn't provided meter readings for them, they had estimated that half of the bill. I replied how would I know to submit meter readings twice in one month if they didn't ask for them but as they had asked for the one reading, I had submitted it. They came back to apologise and offered me £30 after I had asked them to escalate my complaint. I declined and asked them again to escalate my complaint and they came back again offering me £40 which I again declined asking them for the 3rd time to escalate the complaint. Then they came back very passive aggressive to say that the £40 offered was way too much and it was dropped back to £30. I replied that as I hadn't asked for money as compensation I would be again declining and had to ask yet again for the issue to be escalated. I am currently awaiting the outcome of their investigation at the way it's been handled. Its all very odd.
