Can someone please tell me if AGL gas App has the feature where you input your current gas meter read numbers (at any time during the billing period) and it will then give you an instant cost-to-date price please? If i submit a meter reading on the 40th day within a billing period (for example), I don't want a 40 day bill to be issued to me. I just want to be able to see cost-to-date so I can workout my budget.Thankyou
