powercoin italy selling silver coins with rust partial refund only milan italy

 I purchased supposedly silver coin on ebay from powercoin Italy. I was Perry about ordering all the way from Italy but he had all good reveiws. It arrived with rust spots. Now I'm thinking its not even real silver. I let them know, but they had to already know because they sent it. They wanted pictures of it, said it was defective, that the inventory they got was like that. Now the mintage was 999 why would the mint allow rusted silver coins to be distributed when only 999 of them will exsist? I was told to send it back with special instructions to ship it back, check different boxes on form etc. Boxes that weren't even on the form at u.s. post office. Bottom line is it cost me $39.00 to send it back. It cost me $39.00 for the transaction and I received nothing. I left him a bad review on ebay and he asked me to remove it. He said that I was trying to extort him. Never did I mention the word negative or feedback in my correspondence with him. He fraudulently had the negative removed. I contacted ebay and said they didn't know how he got it removed and they would try to reinstate it. I want to let other people know because it costs a lot to ship from u.s. to Italy and you won't be reimbursed with these fritters. The only way rust was on the coin is if it was not real silver, silver don't rust. Hmmmm........
