I have purchased over 75 pieces of jewelry from EBTH. I had a big problem with Samantha the executive. She closed my account. I asked to return a couple diamonds I purchased. As I did not agree with the description. All I asked for was a credit towards a future purchase. She said absoutly no refunds no credits. We had some words and she closed my account. I contacted Gia laboratory they said they can't change the gradings. I have been in the Diamond business business since 1964. I sell on eBay. Over 1 million in sales. Perfect feedback for 22 years. Then I ran into Samantha. And what a horrible experience. Now I understand Why EBTH has such a bad reputation. With people like Samantha as managers. It's no wonder they have so much problems.
