Is there such thing as external mediation if a gov't regulating agency does not want to interfere with a company that does not comply with circulars?

I've read about filing an administrative case but this seems way too costly of a route

For context, I filed a thorough formal complaint to the government agency about a company who may be refusing to comply with published circular/s - which I believe to be enforceable. I had two mediation meetings months ago and just recently.

Both meetings are very heated as the opposing party does not let the complainant finish their dialogue and remains to repeatedly imply that the company's legal team interprets the circular in a way that contradicts both two government agencies' interpretation in addition for the circular being way too vague.

The first meeting ended with an instruction for the complainant to obtain a signed document from the proponents of the circular(s). However, the proponents in those circular are no longer in position but was able to talk to the legal divisions of each respective agency to which they sent an email clarifying about the scope of the circular.

With that in mind, I have requested for the second meeting announcing the complainant's compliance of the opposing party's demand. Again, that meeting became very heated due to it being one-sided and responses being like a broken record in play. The meeting ended with the government agency refusing to give insights of the meeting nor give acknowledgements to either parties - which I am starting to feel like the mediation meetings are biased. The other concern being the opposing company dismissing the document I acquired. It's like they're saying "Yeah great you talked to these agencies, but still our lawyers said that this is how we interpreted it so this is how we will act".

It's a dead end without filing an administrative case (or mediation failure as they said it?). I'm currently seeking the advice of others on what options there may be available in this situation. I just don't get why the government agency refuses to acknowledge there was clearly a non-compliance going on, leaving the complainants to handle such matters independently instead.
