MiWay iRefer

MiWay has this iRefer program whereby they will ask you to refer them to someone who you think might be interested in one of their products and they promised me a R1000 voucher, I referred them and the person took the insurance with them. I think it has been 4 months now I haven’t received the voucher no one from MiWay contacted me I have followed up with an email still no response. I have lost trust with MiWay I am even considering changing my car insurance they are *************.
