Air India — Negligence in issuing boarding pass

Hi, I would like to bring to your notice that I have suffered alot in Delhi airport on 22/02/2022, 21:25 flight AI 839 by the negligence of air india staff. The flight was over loaded with the passengers and they have troubled me alot to issue boarding pass and couldn't able to provide me a seat. They have accepted the mistake of not providing the seat. They issued boarding pass for 23/02/2022. Because of this I couldn't able to attend job and considered as loss of pay. This is completely air lines fault for which you need to compensate it. I'm attaching my airticket. Pls look into it.
