Transaction failed, Deposit stuck, Fee reimbursement please


We made a transaction about a month ago. A security deposit of 0.0020 BTC was withheld but the transaction timed out. We tried to contacted you or an arbitrator by opening an issue in github but we still have had no response and we cannot seem to find the issue either open or closed. Could you please advise on when we should expect to be reimbursed?
