I haven&#x27;t had a gas bill from them in 5 months because their system wouldn&#x27;t let me put in my gas readings. I had to go through a painful 40 day complaints process to get anyone to put them on the account. Never heard back from anyone. Eventually someone on their twitter feed was able to fix it over the course of a day, but of course it will be 3 months before their system generates a bill from the new figures. I&#x27;ve had plenty of ASP.NET &quot;error occurred in the application&quot; pages too so clearly they aren&#x27;t building their site in Release mode. Overall, best described as a clusterfuck.
