All completed blockchain transactions are completely irreversible. This is an inherent property of cryptocurrencies. Unfortunately, there is no way for us to retrieve your lost funds.

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.
