Bests & Worsts Reviews from Amazon

I had a carpet stain from an air purifier that wouldn't budge with my typical store bought, go-to product. With all the positive reviews, I thought I would give this a try. I followed the instructions and tested it in an inconspicuous spot for color fastness. No issue, so I proceeded to spray it on my stain. It not only lifted the stain, but it also lifted the color of my carpet. Now I am left with an area that looks much worse than when I started. And what is up with the NO RETURN policy for this item?? My next step is to contact the company, as it states (on the back of the bottle) that it comes with a 100% money back guarantee. I contacted the company and they said that they do not sell their product on Amazon. Therefore, I do not qualify for the 100% money back guarantee.
