Vintage Hardwood Flooring

had this floor installed just over 1000sq. ft. jatoba dark flooring very rich looking. This was in a new house and after a month some board started splitting on the ends. The floor smudges and scrathes easily. The rep from Vintage flooring came and said that it was nothing to replace 15-20 boards. One insaller came a couldn't get it done properly. If we knew the floor would be this bad we would have never put it in. We have asked for the rep to return but haven't heard anything after two weeks.
