Flight from Dallas to New York to Helsinki: expect the bags to be left in New York

I have flown twice this route from and both times I have had to exit Helsinki Airport without bags. Both times I have also had to experience the lower than expected service at Helsinki Airport.... They are arrogant, they do not care about your issue, and frankly, you do not exist to them. This time they did not even care to call me the following day to let me know that my bags arrived.... They just dropped it to the office... Anybody could have received my bag claiming it is his or hers... Huh... There is lots to fix in the company that takes care of the lost bags...
