The first thing you need to do is to open your iOS app and immediately block your card to avoid possible fraud. To do that you need to:
Go to the Cards tab, find the card you want to lock.
Tap the Settings icon on the top right corner.
Choose Lock your card and then tap Lock.
No worries, you can unlock your card any time you want by pressing the Unlock button in the Settings.
Then please check everything one more time to make sure the card is really lost. If you didn't find the card, please tap the Unload button to withdraw funds back to your Cryptopay account. You can find the detailed guide here.
Contact us via chat or at email@example.com so that we can close your card. We'll also be happy to help you to issue a new one. Please note that the fee, in this case, will be 15 EUR/GBP.
