Hi! I see you're encountering the error message "Invalid Transaction Cardholder Verification Rejected. AVZipOnly" when trying to add funds to CSCPay. To help you better, could you please tell me if you recently updated your billing address or credit card information? Also, are you entering the full billing address and ZIP code exactly as your bank has it on file?

This error usually relates to an Address Verification System (AVS) mismatch, particularly with the ZIP code. AVS checks if the billing address and ZIP code you entered match those on file with your card issuer. If there’s a mismatch, the transaction can be rejected with the AVZipOnly error.

Here are some steps you can try to resolve this:

1. Verify your credit card billing address in the CSCPay app. Make sure the street address and ZIP code exactly match what your bank has.

2. If you have the option, update your credit card details in the app to ensure no outdated information is causing the issue.

3. Avoid using abbreviated forms for street names or ZIP+4 codes; use the full standard format.

4. If you’re using any form of digital wallet like Apple Pay, try using the card number directly instead, as sometimes wallet address data can cause AVS issues.

5. Restart the app and try adding funds again after these checks.

If the error persists, it could also be related to how the card issuer is validating the transaction. In that case, contacting your bank or card issuer and informing them about the declined transaction may help.

Would you like me to guide you through updating your billing address in the app, or is there any other specific detail you want to share about the transaction?
