I did my project last summer(July to Oct 2015), I have several pieces of stone left and want to return to them, but they will not accept because it is their policy to return in 90 days. The stone I return is in perfect shape and has no damage. I said I have no use with the stone left and it is a waste of my money, the boss said he can do nothing. I am not happy and will never do business with them. The boss said he don't care. If they don't care, why you must do it with them? Find someone else!
