Clearance certificate department poor service

When i started using your services in 2019 your customer service was always available to assist. I paid the last debit order at the end of July 2021 according to your payment plan. I have requested clearance certificate from the beginning of August 2021, end of August i called FNB to be told of the outstanding balance. Which i paid and send proof of payment to *** email and on portal. To this day your portal still indicates the same outstanding balance and nobody from clearance certificate department has bothered to communicate with me. But I'm sent this Ticket ID:336597_Ticket Received - DB Missed Rehab Payment
