My fiance ordered a dress from Amazon that was shipped by the seller from China. She then attempted to return it per Amazon's request back to the seller in China. Amazon claimed they wouldn't issue a refund for the return shipping or the dress until it arrived with the seller. It sat with China Post for like a month, then mysteriously ended up back on her doorstep. She then spent another 3 hours cumulatively arguing with different CSRs at Amazon before they would issue her a refund, on the grounds that the package bounce was her fault. Through this process she was following their directions, used the shipping label provided, and generally tried to comply. After that and after AZL failed to deliver yet another package to me and the ensuing terrible customer service I received there, I canceled my prime membership and have not ordered a single thing from them since. It's not worth it because you can't even rely on their customer service anymore.
