I paid for 27,000 Lindens but when I looked at the Lindens, I was 10,800 Lindens short. I have to ask my best friend for the 10,800 Lindens. I also paid for 4,000 Lindens. I would like to get 10,800 Lindens back. How can I do that? I even got an email confirming that I paid for 27,000 Lindens. Thanks in advance.
