how do i delete an incorrect credit if i don't know how to correct it?

I am a storyboard artist and have a bunch of credits on IMDB. but there is one that is incorrectly attributed to me that i did not work on. How can I delete this or change it if i do not know who the actual credit should go to? I can't "prove" it's not me but i know it's not me..
