Bad Sanlam Living benefits

I claimed on my accidental cover and disability insurance which I have with Sanlam Living benefits, they are giving me the run around and it's two years now. Everytime I ask for feedback they say I must submit missing documents of which I have and they still want an update report from my doctors. I ask to talk to the superior and she's always in a meeting or on leave. When I do get hold of her, the line is cut. Please help as I'm getting fed up with how they're handling this claim of mine. Where can I get help?
