Thank you for bringing updates here. The transaction was delayed due to the double payment for the fixed-rate transaction. As a result, your deposit wasn't displayed in our database and couldn't be exchanged further. Therefore, it took a while for our team to investigate what happened and finally, return your coins. We've made some technical adjustments in order to minimize the processing time for such cases. Please don't hesitate to contact us in case of any complications - we'd be happy to assist you!
