They have very poor customer service, it so saddening that Octopus wasted my time. Since January this year I've requested house meter readings, till now they have not resolve it. Each time I called it has been the same story from different staff. Recently, they wasted my precious time. They called to book a meter appointment, after I had made calls, and I told them my availability, which was 29th of August, unfortunately they said the was not available, that I can pick any day in September. I sent an email that I am available on 5th, 7th, and 8th September, they never replied untill the 11th of September. Also, I picked the 16th of September as my available day, but to my greatest surprise, they booked 17th of September for me and backed it up with a reminder. I sent an email about it and they apologised. I sent another email that I will be available on 19th and 21st of September, which they acknowledged and promised to book one of the days, but I never saw their email till as I am writing this review. Secondly, I have told them countless times that they should not send me an estimated bill, but they never respected my wish.
