Credit card is about to expire and i have tried for 2 days to update credit card details, but when i go to "update direct debit", it says that direct debit is not available for my account at the moment.
I have been using direct debit since being with AGL.
Thank you for your post and apologies for the inconvenience that you've had.
You are correct in assuming that you would be able to amend your payment details whilst logged in to My Account online, via the 'Manage Account' screen. If you are having trouble with this (despite being registered for direct debit for ages) our service team would love to help you out. You can talk to them right here: https://bit.ly/AGLChatFa4.
Thank you for your patience and we look forward to hearing from you.
