They tried to charge my card 3 days after I mailed the I-175. Chase flagged it as fraud and it didn’t go through. So pissed right now.  Im looking for the next step from here. everything I have searched for comes up as “I-175 declined” rather than just the payment for the form being declined.    I would love to call the lockbox but no phone number.    should I just wait for the rejection notice? Mail them another payment option?
