If you have scanned the incorrect wallet address or selected the incorrect cryptocurrency, and the transaction has already gone through, there is nothing we can do. All completed transactions are final.

If the transaction is still in progress, we recommend calling us immediately and promptly telling us the issue and your location. Time is of the essence. If the transaction times out, it will be sent automatically. To prevent this, you may want to periodically feed a bill into the machine. If we stop it in time, you can receive a refund of all the money you fed for that transaction.
