... that I posted about a week or so ago that was incorrectly described and received in a plain white envelope with .80 cents postage affixed after I paid the ebay seller $3 for postage and the chip arrived cracked .... and the seller claimed that I had substituted another chip?

Well look at what I got in my P.O. Box this morning. How could the seller determine that I substituted his chip for another one if he refused delivery of my returned UNOPENED insured package? Beware of ebay seller Jorge Caro.

Yes, I left the seller a negative feedback and he responded in kind with a neg in retalliation. What recourse do I now have to recoup my $35 winning bid?
