BarryBank -> DAOC account

[an-angel]

3 months ago I started my 1 month free subscription of DAOC, I enjoyed it so I decided to continue playing. I read that Barrysworld had a service that allowed a person to join his/her BarryBank account to their DAOC account to pay for the subscription. I put £12 into my account and signed up on the BWDAOC-Signup page (where you enter the last 5 digits) but, because of real-life commitments, I soon didn't have time to continue playing.

Now I have decided to give DAOC another go but what I can't figure out is how do I transfer my money from BW to GoA ?

Thanks for any help
