There are a few different reasons why your card can become blocked:
1. You had a negative balance when you first tried to connect it
2. You entered something incorrectly (card number, CVV, expiration date, legal name or billing address)
3. Your card is simply incompatible with our system, or there is some type of block by your bank that is preventing us from pushing or pulling to your card.
To get your card unblocked, submit a form here with last 4 digits of your card number as well as the reason why you think it got blocked in the first place. We are only able to unblock your card one time, so if you believe there may be an issue on your bank's end, we highly recommend giving them a call before reaching back out to us!
