They told me I could reenter the same card. And I did. As far as I know it has something to do with changing from a beta billing system to a live one. But thats just a guess from all the reactions combined. I never received a mail stating that was the case, just the (smelly) mail that I should change my billing info, or else something...
I can imagine that transferring payment data from one system to another without the consent of the owner of that data can't be done (legally), or something of the sort. Anyway, I deleted my data and reentered the same and haven't had an email since.
But for future occasions it might be wise for LL not to make a genuine email look like a phishing mail, with all the weird links and all... I'd fire the corporate communications manager, lol. :matte-motes-sarcasm:
Oh, btw in all fairness: thumbs up for the guy on the live chat. That was fast service.
