I asked the auditor (https://fiduciaire-bonnefous.com/) who to contact to make a claim and they said Ronald Kempers himself and gave me his email address...should I post it here?
Cher Monsieur,
Je vous laisse le soin de contacter M. Ronald Kempers. xxxxxx.xxxxxxx@mymetics.com
Avec mes cordiales salutations.

So that's who you send your requests to though I'm not really a lawyer and don't know how formal a request would be.
