Electrician working something knows nothing about

After my leaking solar geyser had been replaced, the new unit installed at a different position than the previous one was, Impetha Solutions was assigned by my insurer to do the electrical connection. Their electrician did not tell me that he knows absolutely nothing about the job he was to perform. He erroneously reported that the control unit (black box) was malfunctioning. I reported that to the insurer and they eventually approved the fitment of a new unit. The electrician then proceeded to fit the new unit without apparently having any idea how it should be done. As can be expected the system did not do what it was supposed to, and I had to have it done correctly by another contractor. The upshot of it all was that me electricity bill skyrocketed, and I was left to pay the price. Stay away from these guys.
