When an automatic payment gets declined, the system will automatically try to pull the charge again the next day, continually until the payment is processed.
Note: This applies to payment plan sessions, membership auto-billing, and Accounts Receivable (A/R) Center auto-billing.
Some options for a member in this situation are:
If the member removes the old/declined card and updates it with new information, the charge will apply to that card instead.
Remove that member from the session, which they can do by ending their membership.
