I'm freaking out!!! My first couple of bills were about $30-$40!!!! This month I got a $245.86!!!!??? Too early for me to call have to wait for them to open but I'm literally freaking out! How does that happen!? When I spoke with a representative she advised me on how "our appliances use electricity even though we don't use them but we leave them plugged in they still use up electricity! Update March 9 2019 my bill is currently $487.83!! Oh Lord and I signed contract with these people! @Entrust Energy I only own one 50" tv a toaster, microwave,stove,blender & a Fridge though !!! New customers wait till you realize what you got your self into. Going back to Direct Energy today!
