Momentum must FALL

Since last year I called Momentum more than three times requesting to update my funeral cover. In all occasions they refused to give me a reference number but insisted that someone will call me and help me update my funeral cover details. To this day no one has called me and I can't stop wondering what will happen should I die or even one of the people I want to add dies. I find this to be very unprofessional and I am very frustrated. I would like Momentum to refund me all my premiums and cancel the policy since it doesn't serve my needs.
