Incorrect suspension

On 9 February 2016 I paid bonitas R 10350 as upfront payment of my membership. As required I used my membership no as references so that the money can be correctly allocated. A month later i.e in March I received a letter from a certain Bobby saying I'm in arrears. As a courtesy because in my opinion bonitas should have allocated the money themselves using membership number I used. I send a proof of payment. As if that is not enough I still receive a notification that my membership has been suspended. It takes me two days of calling \my own expenses\" for someone to say the suspension has been lifted. How do I trust that since on 11 March a week before being suspended an e-mail was sent through confirming the resolution of the matter. Bonitas please get your act together particularly your so called *********** credit controllers. "
