Remove writer credit

For Nodidavaru Enanthare ( https://www.imdb.com/title/tt33075129/fullcredits/?ref_=tt_ov_wr#writer ) 

there is only one Writer and Director - Kuldeep Cariappa.

other writers have been wrongly credited. I tried submitting a delete request but it was declined as the information could not be verified. These writers are not credited in the official trailer as well. Please help in removing this
