Stars are too big Door stuff should be with door stuff not in 3 different aisles whoever designed that stores stupid

So upset right now! Bought a new Kohler Cimarron toilet to replace broken toilet, nd we all know we hate to do such chores....After installing wax seal which is a pain to align, I begin to assemble the top portion of toilet and I notice that it has already been installed before and the hardware is also missing to attach to the bottom of the tank....Someone else has already used this toilet????....What a horrible experience.....Now still have no working toilet and have to go back to Home Depot and exchange when open and redo the whole thing again.....I work a lot of hours and depend on places to give me the items I paid for....Plain and simple waste of my time......Just no more words to explain how upset I am......
