Inkwasi Glass & Aluminum - BAD SERVICE!

I contracted this company to install shower glass & doors, aluminum glass doors, glass ballistrades and a sliding glass door in the bathroom. Everything was measured before installation. Upon installation, all of a sudden the shower glass and doors don't fit, the glass ballistrades are slipping from the brackets holding it on the sides, the sliding bathroom door doesn't slide, it even broke my nails when trying to pull it, the entire patio area has silicone messed on the floor. Inkwasi Glass & Aluminum are refusing to fix the problem after being paid a hefty amount. I'm so disgusted with their service delivery and the owner who's now refusing to fix this. If they were the last company on EARTH to do above projects, I'll rather go without it. They are the most unprofessional company I've ever had to work with. DON'T DO BUSINESS WITH THEM!!!!
