Thank you for the feedback.
I've been trapped by this fault when I wanted to give the CC back to his original owner last year. I have also seen a few posts like yours, "transfer impossible".
Me thinks that WGT has broken something in that process. I thought it was the (missing) mail notice to the new owner containing that link, but since it doesn't work for you there must be more going wrong.
Time passes, they don't fix it, and they didn't answer here, nor to my recent service questions concerning this issue.
Edit: Have to take the weekend into consideration.
Need I say more?
