RainSoft

I got the rainsoft last year of Oct and the salesman said that I don't have to pay interest and I'm paying for it. I also ask how long it take to pay for the equipment for $120 and he said 6 years and now it takes Goddamn 8 to 9 years. None of my family like the equipment. I would love if they take this back and they can take the money for what I pay. Pos equipment.
