I’ve been an AGL customer for over 10 years. Been in my current residence with electricity provided by AGL for 4.5 years. I pay by direct debit. I was recently told by a friend that AGL have upped their direct debit discount. I checked my current bill and I see it there as a credit. I’ve just gone over all my previous bills and there’s never been a discount on any of them for direct debit. Why would I never have received this discount prior to now?
