I agree with you, thanks for raising this, I'm also over the AGL APP.An AGL rep recently confirmed that the Total Cost To Date EXCLUDES THE DAILY SUPPLY CHARGE.So the Total Cost is always understated, and therefore misleading.Other retailer APPS (Origin, Powershop, Energy Locals etc) rightly include the Daily Supply Charge, and therefore provide a "true" Total Cost.So maybe a switch is the way to go.
