Poor service and fine still outstanding after payment

First time using Pay City to pay a fine, and I'm sorry to say the service from Pay City has been poor. I paid a fine on 21 Feb 2025 and I'm still getting threatening SMSs from the Knysna Municipality stating that the fine is now overdue and marked for escalation. I logged a support ticket with Pay City and all I got in return was that the fine is showing as paid on the Pay City system. When I asked them to confirm that the funds were paid over to the Municipality, they just ignore me and don't bother to respond. Please confirm/ensure that the fine is marked as paid on the MUNICIPALITY'S system.
