After you send a trade request, you have a time window to complete the payment before the other party is able to cancel the trade. During this time you need to complete your payment and press the 'I have paid button'. The other party is notified that you've made the payment and the coins will be held in the bond until the other party finalizes the trade for you after seeing the payment in their account. If you paid for the purchase, but didn't mark the payment complete before the payment time window expired, please contact the other party through the trade chat. You can contact the other party and your other existing trade contacts from the Dashboard. Send a message to the other party and kindly explain the situation and why you couldn't complete payment within the time window. If the other party doesn't respond to this request please contact AgoraDesk staff using the support request form and mention your trade ID.
