Modern Granite & Marble Inc

The granite stone installed at my new home is from modern granite, The granite is getting darker and darker day by day. I never seen such kind of poor quality of granite in my life. The customer service is bad. They reception wont transfer the call to concern department or person. They said they are not interested to talk and ask to email so that concern department will contact us. But no one contacted back. In reverse they blamed me the darkness is due to lack of maintenance . They refuse to replace and I felt bad for choosing granite for my countertops. There is a small crack too. Very bad experience.
