Faulty credit on an imdb entry

This inquiry concerns the imdb entry for "Forever Still: Breathe in Colors". 
I have already tried multiple times to correct / delete the faulty data on this entry by using the regular contribution function and submitting the corrections but they keep getting rejected.

Milad Hülshorst (me) is credited there as "light technician". This information is completely faulty. This production was lead by Daniel Jäger (director) who knew members of the band >Forever Still< personally and agreed to make a music video for them. He then asked students of the film school that he was teaching at if they would like to help him on the set as setrunners or general helping hands. Me and other students agreed, not knowing that Daniel Jäger would later put our names and data on Roles that we didn't even have.
On the set I helped in the camera department but wasn't officially part of that department. I didn't even work on lighting at all! Also - Daniel Jäger never communicated with us that he would create an imdb page and put us all on there. There was no contracts nor an agreement between us. It's also strange that many of the students that helped on the set don't appear on imdb at all (Tristan Fuhrmann, Ruken Akar, Marc Gruss, Ann-Sophie Kampa, Maren Link-Nennmann, Hauke Scholz) eventhough they were also present on the set, while others (Max Siegmund, Florian Steidel, Hannah Oesterreich, Milad Hülshorst) appear under faulty roles on imdb. 

Here's the youtube link for the Music video "Forever Still: Breathe in Colors":

There are no credits at the end of the music video, showing that Milad Hülshorst worked on this project. 

As seen in the video description, the helpers are simply listed as >special thanks to< - not as official crew members. 
If more evidence is needed, I will gladly provide any information I can. It would also be possible to contact Daniel Jäger and inform him about this faulty entry. 
As the official imdb submissions I sent were all rejected, I really hope this message will be properly responded. I hope for a quick solution since this faulty entry actively disturbs the integrity of my Imdb profile and my work as a director. I believe it's also illegal to credit people for departments and roles that they didn't work in with their real names. 

Best regards,
Milad Hülshorst
