I recently ran into this tactic to allow CUs to not pay Rewards Bonuses:
Thank you for messaging Pelican State Credit Union!
Due to change in systems, some online-initiated and recurring debit card purchases, such as Sudden Link, are registering as "Bill Payment Withdrawal" rather than "Debit Card Withdrawal." This has caused the reports to not include these transactions in your 15 required debit card transactions.
We are currently investigating this new reporting and will let you know once this is resolved!
In the meantime, we recommend continuing making your 15 transactions, not including the Bill Payment Withdrawals.
We will let all of our members know at once when this is resolved.
Please let us know if we can be of any further assistance.
