IMDB Staff: How to show adequate proof to remove incorrect credit?

I am constantly getting credited for things I did not work on, in roles that are lower in seniority than my current role.  This hugely impacts my employment prospects as clients often look at my imdb profile to check my history in the role of VFX Supervisor.  However, IMDB makes it nigh on impossible to prove that I did not work on something.  I am asked to upload proof as to why I should not have been credited - how does one do this?  

I have uploaded screenshots of the credits where my name is clearly not there, and it still gets declined as 'Unable to verify'.  I upload my Linkedin page, evidence of my current role, but still get declined.

What definitive proof does IMDB accept?  This genuinely is impacting my credibility when my IMDB does not align with my actual role and work history.

I would appreciate any staff help on the best and fastest way to get these corrections approved and not declined.

Thanks!
