Air India — drunk passengers

I took air india flight # ai102 on feb 11th at 2:20 from jfk airport. I have a medical problem with my balance and speech. There were 3 men in the flight who were drunk. Two of them were sitting next to me. They made fun of me and told me that i am abnormal. They were throwing the food and were not let me have my food. They troubled me so much and they were misbehaving with other women that the pilot had to come and warn them. They were already drunk when they came in the flight. One of them was a nypd cop. I took air india for the first time and had so much problem and i will not take it next time. I won't blame the passenger but i will blame the airline. We pay so much and get humiliated. No one from the crew offer me to change my seat. I'm so much hurt by this and more over i had to sit with them for 13 hours.
