AvatarXchange is other site that suppose to be helping people sell/buy lindens. This is my 1st experience using this site and I am very dissapointed. This site got bunch of terminals where I can deposit/withdraw lindens. I withdraw 5000 lindens to one of their terminal and it is successful. The lindens showed on their website in seconds. I try to sell it but with some problems like I dont have payment info in second life I wasnt able to sell it. I try to get the lindens back so I withdraw it from the site. Unfortunately its been 3 days I dont get my lindens and my balance on that site is 0. I start contacting people who is listed there for problems but 2 of them are like 8 months are no longer working with them. I was shocked! That is long and still their name is listed there. They even got a LM for their headquarters but if u go there its a different building already. No headquarter. Can someone please help me how can I report them? Im a basic user only and file ticket i got no option for my concern. I want my lindens back. Sorry for my grammar.
