Legacy Tile review: Complaint

I went to this business (Legacy Tile, 2515 e 15th St. Panama City, FL.) and told them I wanted quartz installed. They showed me a slab, my husband and I liked it, so we purchased from them. After they installed, they started to seal it and I asked why because you don't seal quartz (the main reason I wanted quartz) this is when we found out it wasn't quartz. I was in shock, I never had anything like this happen... What do you do? Tell them to tear it out? They made such a mess installing, all around horrible experience. I had 2 women message me that had the same thing happen to them. I think someone should check this place out. I'm stuck with something I didn't want and paid for quartz, which is more expensive.
