If that is your desire, then ring or chat with AGL and cancel your plan.
Before you do that I would suggest that you find the plan that you wish to change to.
If it is not with AGL then contact the new Retailer and sign up with them. If you have a smart meter it should happen quickly.
If you don't then be prepared to wait for a while a meter reader is sent around to your place.
These pages are supported by non employees like myself and their is NO GUARANTEE that any AGL employee will answer your query.
