# I paid for a machine, but it does not start. What can I do?

On most machines, you can select it again in the app and send it a new start signal free of charge the first 15 minutes after your purchase. How to send a new start signal: https://wiser.airwallet.net/en/article/how-can-i-send-a-new-start-signal-to-the-machine-dbo7kj/

If this isn’t an option please contact Airwallet at  ${color}[#29e1b4](+45 7870 9999) or ${color}[#29e1b4](contact@airwallet.net) and have your transaction ID or phone number ready, you can find the transaction ID on the receipt in the app.

* If you cannot find your receipt, it is probably because you have only booked the machine but have not paid for it yet. You only pay for the machine when you start it.

* If you need a refund, the amount will be returned to your account within 5-10 business days.
