Disgusting service form Constantia insurance. Not paying claims.

I am very appalled by the way Constantia insurance treats its clients. My name is Paul, I am the owner of a duly registered company called Dichaba Kopano funeral home. I have submitted my claims to their claims department in November 2019. Even now they have not pay a single claim. When I call to find out what the problem could be , they're not saying anything. They keep asking for the same information over and over again . They're so obsessed with a certified death certificate. I have given the at least 5 times. They're not paying claims . I wonder if this is because of the colour of my skin or the size of my company!!
