I don't think there's one publicly available, but there's a few ways you can get in touch with them here.
My preference is the AGL App, works like e-mail, but more modern e.g. a messenger app. I love it!
Hi @KP75 , we don't use email for general or customer service queries, but the Messaging feature Panda mentioned above basically works the same way as email - there's an ongoing record of your conversation, and no need to wait around for an agent to reply.
This forum is more-so for general information. For a specific request for your account, you should contact AGL here.
