Poor service by Standard Bank homeowners Insurance

I had my solar geyser replaced by Standard bank's contractors : Rimitsu CST Enterprise. Since then my solar geyser has been spewing out hot water. I complained to the bank about the problem. The plumbers they sent out said that the previous plumbers did not connect the pipes correctly(RIMITSU)I call them daily for the problem to be solved. Since the 2nd of May 2024 no assistance has been received. I am losing water and electricity. Will standard bank compensate me for my loss? When will the issue be resolved?
