Problem with refer a friend account link

Hi There,

I thought I would come on the forum asking for advice or help on how to resolve this issue.
I recently signed up to a new b.net account to use the refer a friend offer, unfortunately I was dumb enough not to use the authentication key that was emailed to me, instead I saw there's a trial version of WoW already in the new b.net account and thought that was automatically linked to my veteran account .

I paid digitally and activated it to the full version, and then found out it wasn't linked properly.
So now my new b.net account has a WoW1 (paid / nonlinked) and WoW2 (trial/linked)..is there a way to resolve this??

Thanks
