Cold Showers For a whole month

On 1 March 2024 my gyser started tripping my main switch, I called Standard Bank Insurance to log a claim, the plumber came in and fixed the incorrect gyser. I had to log a new claim after a month and the gyser is still not fixed. A whole month of cold showers is unacceptable. Whenever I call they always tell me that they will call me back and they never do. As I type this I’m on hold for the second time today.
