AGL - Australian Gas ( New South Wales, Australia)
I received a gas account together with a leaflet alerting me to the fact that "We've upgraded our customer management systems". This involves changing BPAY details. Two days later I logged onto my bank to alter the BPAY details and set up the bill for payment. It would not work. Called AGL and was told: Yes, sorry the bank has not yet got the information it requires to make the changes happen. It should be all right by tomorrow. Try again next week. This is not just my problem, but that of thousands of customers. This bad customer service should be publicised. AGL should be shamed. Can you do that?
