We had them install a windshield in our 2016 Land Rover. Everything was good until we noticed that the windshield slide down a little bit. We contacted them and stated our concern. The owner of the company actually called and started accusing me of not being home when install occurred. Then proceeded how it was our fault that the windshield looks the way it does. Poor customer service and absolutely not a problem solving company especially coming from the owner who I thought would help us.
