Standard Bank Insurance failure

I have a solar geyser which I had installed through the bank. 2 weeks ago the geyser burst. The geyser is still under warranty so it has to be replaced. Where the problem with the bank comes in is that the insurance department has taken 14 days and still I am boiling water on a stove and have no geyser. We contacted their complaints dep. and lodged a complaint with them and still nothing is being done to resolve the problem. This is the worst service I have ever gotten from any bank which service is concerned
