Thank you for your reply,appreciated. However it's not a payment error, it's on the billing tab/option on the app that doesn't appear at all for GAS (should be under Electricity in the screenshot to then tap in & go to pdf bill etc).Keep getting the error messages as per screenshots.IT department are now investigating after seeing these posts which is great, however I gave to wait a week as the staff member looking after this case is going on leave effective tomorrow.......so I waitthanks again ...
