Worst service

I have a 3rd party claim with discovery insure since May. I have been calling day in and day out but the person whom my claim is assigned to is not taking my calls or answering my mails. Stephen Van Niekerk is the person my claim has been assigned to and I must say the service he is providing is the worst. Discovery is a reputable company but with the experience I am receiving from this guy has surely damaged your reputation. I have a 3 weeks old baby and I need my car to attend doctors appointment but I can't because I don't have a car. I was offered a 60% settlement which I have accepted more than a month ago but still discovery is failing to deliver.

Can someone of higher authority sort this out today, I have ran out of patience and I am frustrated. My claim number is ***.
