This is a generic "processor decline," which means your bank does not accept this transaction. Our payment processor does not generate these declines, they are directly received from your bank.
You will need to contact your bank for more information to better understand why they are sending us that response. Generally, we recommend contacting the bank's technical support or tier 2 support since this issue requires more access than frontline support is typically granted. Make sure to contact your bank before attempting to purchase again.
