If you've just blocked your card after 3 wrong attempts to use your PIN, you have two options:
Go to an ATM from a major bank, and you should be able to see a new 'PIN Unlock' option or you can otherwise view your remaining amount. Third option would be to withdraw cash.
If it doesn't work, please contact our support team to ask our banking partner to unblock your pin tries (0-3 days). email@example.com
