Everyday this company rings me up told me my invertor was a fire hazard. come out to check my invertor and paper work they tryed selling me a new invertor. when they left my invertor has stopped working. i called in another company said that they had turned my scheme off nothing wrong with my invertor. i would advice anyone not to trust this company.out to make money. im 87 and i dont want to spend anymore money.ive reported this company to trading standards. lets hope they can do something.how many other people have they conned doing this.all i can say is just hang up on them
