Do not have an option to remove a poster/image

Indian film "Dacoit" starring Adivi Sesh and (now) Mrunal Thakur in Main leads; has a picture/poster of Shruti Haasan (initially cast) while I have uploaded new posters with Final cast members, I do not have an option to takedown/remove misleading posters.

Please help me take down this picture/poster:
