Bad Service at Outsurance

I have a policy at Outsurance, (for many years), service was excellent, but I'm not sure why this bad service...... I have referred a customer to Outsurance in November 2018, we could not get through to the telephone lines that day, so I chat to Anna on my Outsurance portal, gave her Mr Graham's cellphone no so that Outsurance can contact him because he needed insurance on his vehicle, Outsurance called him and he indeed signed up that day, his installment went off his account in December 2018, so I talked to several people at Outsurance on several occasions that I am due for a discount because I got them a client, so I was told last year that his installment 1st need to go off, as it did, then I will qualify for R400 discount end of January 2019. So today after several people I talked to I was told Mr Graham signed up before I refered him. Can you believe this nonsense, Outsurance phoned him, after I gave Outsurance his details? This is not acceptable to do business like this!
