Hi,
I bought product from auctiva user using ebay,but when i click on the link sent from ebay http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=25...=ADME:B:EOIBSA:UK:31 .i'm wondering what is going on.Please help!!!

Looks like eBay has pulled the listing.

When something I have bid on has been pulled I have received a mail from eBay.

Is the seller still registered, if you have not paid then you are under no obligation to complete, if you have and have not received the goods then if by PayPal claim it back through them.

I'd pay but after that writes that user is no longer registered and the listing are closed.Is that means that i'm f****d up!!

NO do not pay..if the seller is Not a Registered User you are under no obligation anymore. Instead, file this report:
