Worst service from an insurance company!

I called yesterday at 13:00 requesting feedback as to why my premium had gone up. The lady I spike to said no problem she would get back to me. I called this afternoon at 16:50 as I had not heard from that lady. I was put on hold for 5 min and then I asked for someone to call me back urgently, she said that she would do so. I waited and no call, I then called and for hold of Siniele who promised that he would ensure that the b a Lance from R511 and R540 would be taking off next month's premium and that my premium would be adjusted back to R511. Sort this out or I will take this further and cancel! Call me back urgently, I want confirmation!
