Mercari MERCARI DENIED CLAIM & DELETED PROOF OF TRANSACTIONS San Francisco Internet

 I sold two bracelets on the Mercari app. The buyer made false claims to return the bracelets to me, which Mercari granted her permission to do so, even though everything was exactly as described. The buyer even said to me she wanted to keep just one of the bracelets (a $675 value) but not pay the price. When the packages were returned to me, I knew one was empty, so prior to even opening it, I video taped and took pictures of myself at the post pffice examining and opening the packages. One was completely empty, the other has the $125 12k bracelet, not the $675 bracelet. She not only lied to get her $800 back (which mercari allowed) , but sent an empty package! I thought video taping and posting ro youtube would be enough proof for Mercari to reimburse me, but it wasn't. 2 videos and endless photos and they said I didnt provide enough proof. Then, because of their mistake, they banned me and are deleting my account (basically because they don't want me to cause trouble or complain, even though I did NOTHING WRONG!) The video clearly shows me examining unopened packages from the buyer and slowly opening proving one was empty. Even the corespondence with the buyer shows she knows she did something wrong. Mercari is so dishonest, that they claim all the proof I could possibly provide wasn't enough. They absolutely need to reimburse me the $675 as I provided all the proof humanly possible, did exactly as they asked and was ripped off by the buyer. Just now, Mercari deleted the transactions, like they never existed! Luckily I took a screen shot of every single convo and interaction with the buyer and Mercari staff as I went along. Absolute thieves!
