This is the kind of email to look out for. It's clearly not from ebay. Stupid fake emails!
Quote:
Dear Value Customer,
We are writing to alert you that your balance is not paid, because your
debit card issuer declined eBay's attempt to charge your card with your
monthly invoice amount.
To speed up this process, you are required to verify your personal information.
O n l i n e C u s t o m e r S e r v i c e
As a courtesy, eBay will automatically make a second attempt to charge
your card. This attempt will take place in about 1 to 5 days.
Regards,
