While I commiserate with your experience I'm not sure you should write off a whole country. Asking for a mis-declaration of shipping value and/or shipping to a US third party are par for the course in many overseas transactions
Rather than blocking a whole country (or for that part continent) a better policy may be in future to state your overseas shipping terms i.e. "customs value will be declared at the price sold and no third party shipping"
And if UPS have a record of a signature (no matter who signed) then as far as you are concerned the cables were delivered -- I believe AudioGon (and PayPal or whomever you received payment via and shipped with) should side with you in this regard
