I ordered a golden ring with diamonds and paid for it 188$ by credit card Visa as of 11 January 2012. I received an item from apexjewels.com of 28 February 2012 that does not match the seller's description. I ordered a ring with the width of 3.5 mm but I received a ring with the width of 2 mm. One stone in this ring was damaged. The price of the ring with the width of 2 mm is sufficiently lower than the ring with the width of 3.5 mm. I ordered this ring through official site of this seller.

I have sent this ring back to the address stated by the seller. According the tracking number, this ring was delivered to the seller by USPS.com as of the 10-th of February 2012.

But the seller wrote to me: We are not yet still showing the receipt of the return. I still didnt receive the refund. I have copies of email conversation with this seller, payment receipt which confirms that I paid for the ring as of 11 january 2012, and tracking number  to track that I sent by USPS post the ring to Apex J
