Air India — the extremely poor condition of the plane

I left saudi arabia last night at 11:15 pm last night with air india flights. It was my first time in the flight after a long time, but i can without a doubt say it is by far the worse flights in the world. The lavatories got flooded.
This is what happened:
Since i was late to board the plane, the air steward asked me to place my back pack on the carpeted floor of the plane till the plane took off and the seatbelt sign was switched off (Which didnt happen for about 20 mins after take off, maybe even more). The entire plane reeked o[censored]rine so by the time i had a chance to get to my backpack, it was soaked with urine. It contained my power bank and my laptop.
The backpack is going to trash now. I am throwing it away. Its in that kind of condition that it cant be salvaged.

I really hope you do something about this and i am expecting some action to be taken immediately. This really has been the worst flight. Your airlines are the worst and im definetly never going to be your customer again.

Sincerely,
A former, disgusted customer.
