When I called for my registration papers I was informed that AVAF was experiencing a backlog due to the system having a backlog of clearing payments received. </p> <p> </p> <p>If I have settled my account in full why am I still getting debited?</p> <p> </p> <p>I want my money back.</p> <p> </p> <p> </p>
