Update:
As of right now, the seller's store on the MP has been shut down and removed. All items have been removed.
The seller DID contact me on my review of his item, earlier today, and when I asked for a refund there, he did not respond. Either he deleted his entire store himself, of LL did. I don't know.
It saddens me a great deal that the only money I had...was stolen from me. I know 6000L$ might not sound like a lot of money to most people, but to me, it was the first spending cash I've had in over a year. I'm really, really disheartened by this situation. Now I'm left with an avatar that has nothing because I invested in this 'mesh avatar' instead of buying a skin/shape etc.
I appreciate the input and everything from everyone. Today was my frist day back on SecondLife in a long time. It has left a very bitter taste in my mouth, sadly. I had looked so forward to coming back...
