There are several possible reasons. To successfully complete the exchange, please ensure that you have completed the following steps correctly: 1. Check that your transfer details are correct. Incorrectly specified details may result in an "Error" status for your order. You will receive a notification by email explaining the reason. 2. If an order is processed using incorrect details, a refund is not possible. It is recommended that you carefully check the information before starting the exchange. 3. Make sure there are funds in your account. If there is no writing, the order will not be processed. 4. Transaction delay may be caused by the blockchain. In this case, nobody cannot speed up the process, so we can only wait. The reasons may be different. If your case does not meet any of the situations from above, please contact us through the support section of our website.
