R1000 discount on policy outstanding for months

I contacted your offices on 29 May 2018, regarding the R1000 discount to be loaded at the end of May 2018 which did not happen at all after a i referred my father to Outsurance via your app. I was promised to be phoned back. Nobody contacted me. A week ago again I contacted your offices and i received a firm confirmation that the R1000 discount will be app**** on 28 June 2018. This did not transpire as a discount of only R460.01 was app****. I contacted your offices twice on 29 June 2018 and every time i get told we will revert back to you as a manager is looking into the matter. This is no longer acceptable and thus tantamount to false advertising and empty promises from Outsurance as you as Outsurance have no commitment on the latter as you are clearly delaying the process and have no commitment to honour your obligation towards me as the client.
