Hi Hans,
Welcome to the AGL Community!
If your account is in credit then you're well within your rights to request that this be refunded back to you! Unfortunately, we can't arrange this directly through the AGL Community I'm sorry to say. If you log into your AGL My Account you can chat with a member of our customer service team via instant messenger who'll be more than happy to arrange this for you.
Kind regards,
Jayden
