Complaint Review: James Weitzman And Susan McNaughton

We saw the following computer advertised in Craig's list and contacted the seller a susan Mcnaughton, details below. She claimed she was selling this computer becuase she received a second computer as a gift from another person and wanted us to make transactions through TNT. She sent a web link to TNT site that informed us of the guaranteed transactions. Accordingly, we received an email from TNT saying tht the computer has been received and we should make payment. We paid $475.00 and $50.00 transaction fee at Western Union and thus far have not received any goods.
We were told that the computer would be delivered in 2 business days and only after we are satisfied with the goods, would TNT release payment. Please see correspondence below.
However, thus far nothing has materialzed. Western Union tells us the money has been paid to a Mr James Weitzman. All of these appear to have some address in Wolverhampton UK.
We are highly suspicious this is a scam and we have been duped. This is highly fraudulent that we trusted your company TNT and its transaction promises, but nothing has happened. We are very worried.
Please advice us.
Thanks
