Unfortunately we cannot force accept a payment option.
The system un-verifies you after too many failed card attempts for security purposes, and locks you out for 1 hour from your first failed attempt.
If you have tried adding a card and have been stuck in a verifying and un-verifying loop please let HONK support know - we may be able to assist.
Outside of regular business hours you will have to wait 1 hour from your first failed attempt to try again.
However, some cards will never be accepted by our system (for reasons beyond our control).
