Worthless product

I have also been arguing with the retailer and manufacturer for the last 2 years. Two weeks after the floor was put down, several "chips" appeared in one corner. I was told to get some nail polish and paint those areas because they would fill with dirt. Seriously?! Since then, I have about 30 little chips out of the tiles all over the floor and one big chip by the stove. Every time I wash the floor, I find another chip. The manufacturer is saying it is impact wear/damage. In other words, from people walking on the floor. No one in here wears heels and there are no animals. In fact, most of the time I am the only one here. Congoleum's people came out with all their fancy equipment and cameras and that was their conclusion. Also, the grout is all cracked and they are blaming that on the humidity in the house although I do not run a dehumidifier or a humidifier. I live in Columbus, Ohio where we simply have 4 regular seasons. Congoleum does not back up their product and what good is a floor if you can't walk on it? I had a regular vinyl floor down for 20 years and had no issue at all. I just wanted to update the kitchen. This was quite expensive and I wish I had done regular ceramic. I will never buy from Mohawk/Congoleum EVER again.
