Discovery Insure terrible service over and over again with false apologies

I wrote a review about how I could not get hold of discovery to lay a claim. They then got hold of me on the 22nd of Feb and apologised for their poor service. The very next day on the 23 Feb they came and collected my microwave. I was told that someone named, lets call her Ms K, from Discovery would keep me infomed on what is happening with my appliance and claim. Today is the 14 of March. Not a call, sms or email. Who should I contact to get this sorted out since your dont respond to emails and just dont answer the phones. But you nicely take our money on time, I dont ghost you, why are you ghosting me.
