If your payment is declined, there is unfortunately nothing that Strongest can do to force a payment through. However, in many cases, the error codes can be helpful. For example, if the error code asks you to enter a CVC, make sure to enter a CVC for your charge to complete.
We have also found that often times, debit cards will have strict fraud protection, particularly for international purchases. If you are outside the USA, we recommend that you complete registration using a credit card rather than a debit card.
You may need to call your bank to get more information about your declined purchase.
If your purchase was declined and you have already spoken with your bank, please send support@strongest.com a screenshot of the error message you see, along with the competition name and division that you are trying to sign up for.
