biggest pain in the ass every. he made a mistake when he chose necklace size. He chose the smallest length because eBay's system showed that it was the most popular option of ther buyers. Because the sale was international, we suggested a low cost solution to resolve it, but he harrassed us with over 20 messages to pay for expensive international air mail parcel because he MADE a mistake. Talked to eBay customer service, and eBay said that he should be responsible for return costs in cases like this. When told many lies when he filed his return case. I am glad that we have all the messages he sent to prove our case.
