LOT Polish Airlines review by raluca

I had a bad experience on board with Lot Polish Airlines company: my hand luggage was moved from where I put in the cabin it without noticing me. When we landed, I asked the stewardess where is my luggage and she was acting like she knew nothing about it. One person said he saw her moving the luggage. I talked to her again, I explained again the situation but she was too busy flirting and joking with the other steward, rather than hear me or help me and then she gave an answer just randomly: that my luggage is in front of the airplane. I went to the front of the airplane, asked the other stewards that were there and they said that maybe my luggage is in the bus. It was not, as I was looking for it in the aircraft. I went to the first stewardess - in the back again and asked, meanwhile my friend started to look in all the compartments again and found the luggage that was intentionally moved by the stewardess. What should I understand from this type of behavior ?
