I had ( still have !)several questions that l would like answered before changing to Octopus . No response on telephone helpline . I suspect it is unmanned. A generic response from an email which gave no information at all . A generic text message arrived giving me link to sign up with . None of the above provided answers to my queries that only human interaction can provide. I like the claimed ethos of Octopus Energy but as far as impressing me enough to sign up with them they look like they are failing at the first hurdle. Terrible customer service!
