Investigate portal credit card payment after PAC failure

Look into whether a client could make a credit card payment through the portal after a PAC failure.

Context: for 7161 Laurel Creek Dr, Stockbridge, Georgia 30281, notes say the client called because a payment receipt was needed. One report says only an email was sent to Guardian about taking payment, while history indicates the system PAC failed and then allowed the client to make a credit card payment.

The question is whether this flow is possible through the portal, and if so, how that credit card payment could have happened. There is also confusion around Guardian guidance about using the correct process.
