Ellectrical fault

I had problems with my Geyser not supplying hot water, of which I placed a claim with ASBA. A plumber was allocated, and they said that it's not a burst geyser, but an electrical issue. Digicall Assessing Solutions PTY was allocated to handle this matter. sai it's not a burst geyser, but an electrical issue.. A electrician came in on Friday and said that it's a geyser time and reset it. Since then, my ower goes off as soon as you switch on the geyser. I lodged a complain on Friday the 20th and been following since then. I have been sending follow up emails since yesterday, but not getting any response on progress.
