I am a US Naval Veteran, and I purchased a one-of-a-kind pair of 18K Gold and Onyx cuff links while on deployment in 2006 in Dubai. They were purchased as a gift, but I ended up never giving them to the recipient, so I recently decided to sell them on eBay to help pay for my upcoming wedding.
I placed the item on Ebay, and after 2 hours, ebay user 2formeoneforyou (Renee Budz) purchased the item for $300 using the Buy it Now option. The item was paid for and shipped via Ebay using delivery confirmation. The delivery confirmation on the item was verified as delivered. Shortly after, Budz claimed that the item was not received. I placed a call to her Post Office, who verified via her carrier that the package was delivered. She continued to claim the item was not received and her mail service was "bad".
She initiated a refund, knowing as an experienced buyer that Ebay would process the refund because of the high dollar value of the item.
