Here are some possible scenarios that may cause this:
Your card may not be linked and verified on HeyMax yet. Be sure to link and verify the card before making the payment. This is only available for Visa cards.
There’s a small chance that it may take up to a month for these transactions to get tracked via Visa’s network. This typically happens when the merchant's acquiring bank is the same as your card issuing bank.
The merchant may have certain exclusions (e.g. location restrictions). Be sure to read the terms and conditions on the merchant’s page on heymax to make sure your transaction is eligible.
