LinkedIn complaint: Disgusting service and support

We are a voluntary organisation focussed on diversity, equity and inclusion. Account was opened for several days without issue and started to grow at a rate which exceeded our expectations in terms of followers and connections. The account was abruptly placed on restriction and we were effectively locked out. We then received communications back and forth with someone from their security team saying we were unprofessional and content was inappropriate. We asked for specifics but nothing has been provided just referrals to their guidelines which we have not breached. We have tried to explain but the person we are dealing with “Lupin” (I doubt that’s their real name, perhaps they’ve been watching the French Netflix series of the same name) is very frosty in their responses, a disregard for what we are saying and provided no reasonable level of care. Really disgusted with this one individual is is stopping a voluntary organisation from promoting a message of positivity and addressing bias and discrimination.
