I'm just in the process of leaving Octopus, they hadn't billed me since Nov (7 months ) even though their FAQ's state that they will bill, even just with estimated reads, ever three months. I requested a bill, heard nothing from them, still no bill. I sent in up-to-date meter reads, to trigger a bill, the FAQ's stated this should happen within 48 hours... 2 weeks later...still no bill. After numerous further emails... I approached another firm and stated the process of leaving, so at least I'd have a final bill. suddenly Octopus reached out, apparently if I explained yet again, what was wrong they'd solve it, just give them 5 days.. 6 days later.. nothing. I finally called and a lad pressed the button to generate a bill.. wow...it was that simple. But I'm still leaving. If they can't get the fundamental basics right, such as generating a bill, the absolute basic requirement of the company.. I have no faith they'd be any good with more complicated issues.
