But my transaction has not been completed, it is "pending" on the exchange and the transaction will not be completed. Did I still lose the coins? The trx tron address to which I sent the ada cardano is from my binance account. Do you think that even with the transaction pending on the exchange and not being completed, I still lost the coins?
If the transaction hasn't been sent out, yet then customer support can help you cancel the transaction and refund your account. The only disadvantage you have now is that customer support is slow in responding to the issue, but I believe the solution is easy at this point, and so they will be able to help you. Don't lose hope yet.
