Absolutely no interest in a claim!

Santam Insurance is putting my whole family at risk by refusing to fix my water leak. They have sent somebody to my house to access the leak only after 3days and then have just disappeared. I have a Covid-19 (Corona virus) positive person in my house and no means for anybody else in the household to to get any sanitation. We are living in fear of our lives because of incompetence. By refusing to give me any information or to fix the leak my whole household cannot protect themselves from the virus. I am told that the maximum water leak that will be paid is R1000 which has already been exceeded so I cannot turn my water back on. Nobody will answer me as to when I can get return visit from a plumber?
