BEWARE!!!!

I just read another complaint on Hello Peter for something similar I am experiencing with this company. I am not surprised that they do not respond. I had no hot water and after a plumber was send out I was told that there was no power to my geyser. An electrician came out, I was told that there was a problem with the earth leakage, that they had to replace the main switch, a new cable, to rebalance the distribution board and an earth leakage protection unit. They told me the cost will be R6998, and had to be paid immediately. I was under the impression that the amount of work they had to do will take at least 3 hours because of all the faults they found. I was very surprised to see them finish everything within 40min! I was told that a damages report will be sent within 48 hours to claim the cost from my insurance. It is day 3 and I am still waiting. I still don't have hot water, they promised to be at my house late afternoon.... not holding my breath. Do I sue to get my money back?? For anyone considering using this company please use someone else! I have a gut feel that when they saw they are dealing with a woman they just ripped me off.
