STILL RECEIVE STATEMENTS AFTER PAYMENT

Please explain to me the following. On the 30 of March I received an outstanding traffic fine. I paid the account. On the 11 May I received an email from Aqeedah Hendricks confirming payment. She also advised me that they are dealing with many different government departments and the process can take 3 - 12 weeks for your receipts to be issued and the fine to be removed off the various 3rd party websites. My payment reflected on the 3rd May on their system. On the 21 June I received a statement with the same amount and offense date. PLEASE PLEASE EXPLAIN TO ME what is happening at your offices.
