I already had a lindenlab support! "Jagix Linden" did the best to try to help me, and even managed to locate my item that was sold and sent me, but it was an empty box and without the contents that I had inside. But, I believe lindenlab's team did their best to try to resolve the case. I consider the case closed, unfortunately what I sold had already been opened by the buyer and removed the content. But I'm sure that was solved.
