Today I purchased $80.00 worth of lindens and never received the lindens it shows in my bank account the transaction has been paid. How do I get my lindens. I have bought lindens from here for years never had this problem before. I looked in the account history and it shows I paid for the lindens then it shows payment credit I dont understand why I havent received my lindens. thank you for your time Imzati
