that's a bit excessive to call them scammers, isn't it?  if they were scammers they would have just taken your money and never send you anything at all.  I've had 3 successful orders from them for what its worth and many people have a LOT of octominer rigs.  I doubt they would throw their reputation in the industry away for 1 small order mistake.  It doesn't seem like their fault the customs in your country rejected the package.  They should obviously refund you and I expect they either already have or will be.  Thanks for bringing this to our attention regardless, hope you get your money back.
