Quest Interiors - Oshkosh

I had FloorQuest install Porcelain tile in my master bathroom a couple years ago. I us*** FloorQuest for several products when I built my home and it was nightmare dealing with the owner/manager ***. They wouldn't take responsibility for damages or poor workmanship around the home. Absolute nightmare. I've been terrifi*** to go back to see if they'd come back and fix all the issues that still weren't fix*** from when they install*** everything and when I did it was a little over a month ago and talk*** to a manager nam*** I explain*** to him I had a bad history with *** and didn't want to deal with him and only want*** a resolution. *** said he would have to have somebody come over and look at what I was explaining since it wasn't a cheap product and last year the surface of the porcelain began to peel on the corner pieces. *** said that wasn't possible and he'll contact me to schule something. Nobody contact*** me so today 4-17-19 I went in and talk*** to *** and brought pictures of what I told *** about and she was very helpful. I explain*** my past relationship with *** and how poorly he treat*** me and my home and only want*** a resolution for the defective product. *** something was defective since it was only the corner pieces and want*** to come out as soon as possible to have somebody inspect the tile. A couple hours later *** email*** me (which I was really hoping to never talk to again) and told me I ne*** to "paint the porcelain" and told me to refer to the manufacturer's website. I can't even contact them because they're in Italy. There's no contact number I'm able to email or call. *** has all the information from what distributor he gets the product from. I've search*** and search and the only thing I can find is I have to process any defective or warranty issues with the place I purchas*** it from. He wont stand up or take ownership for the bad product they install. This is why I didn't want to go back in because I knew I was going to be treat*** this way. I don't know what to do anymore.
