I do NOT recommend Dodo Internet.
Impressed at the thought of saving money from my pension by having ISP, electricity and gas from one source, and looking forward to learning how much I'd save, I signed up. The email I received back told me nothing whatsoever about the joint billing and in fact led me to believe that it was going to be quite a lot of work ensuring I got the discounts. Within ten minutes of their email I had written back withdrawing my application for all three services.
It took daily emails from me to extract from them confirmation of my gas and power accounts. Their Internet section has not only NOT acknowledged that I have withdrawn, but have told me I will be billed $75 a month and how happy they are I'm a customer.
I did point out that it's not possible for me to be such as my modem is not from Dodo and I am not electronically connected with them; but that drew zero response.
Not only has their Internet section not refunded my $60 but I'm pretty sure they mean to start charging my card in a few weeks' time. They are impossible to deal with.

At this stage I'm recommending them for their pre-sale customer service, which is top class.
When I receive the goods, I expect to be reviewing those in the same way.
