Southern Railway — Change in coach position in platform 8 of tambaram railway station

I am travelling in kanyakumari express on feb 9, 2022. I was waiting for the train in platform no. 8. The announcement said the coach A2 will be in coach position 17. But when the train came A2 coach was in position 19. This is not the first time.. Even for the previous journey the situation was the same. With luggages aged people and people with children suffer great difficulty. Kindly make necessary measures and make passengers comfortable.
