Twice over the last couple of months I've received emails that look like they have come from eBay asking me to verify details, the first one my account , the second to update my billing details.
Luckily, I got suspicious and queried the first email where I was told that yes it was a fake and to send the details to eBay.
After this I query all emails from companies asking for my details, just contact the company and they will either confirm or deny sending the email. If you do have a query about an email from eBay or Paypal, go to the site map link and find 'ebay.co.uk safety centre' or the 'Paypal security centre' under the heading 'Marketplace safety' and follow their instructions.
Don't let the conmen/women win, fight back, you earnt your money through hard work don't give them the chance the nick it.
