Are you speaking about the agent or the omc? If you speak about the agent, you could ask the OMC to consider a new one. If you are speaking about the OMC, you are already part of it, you can volunteer to become director, secretary or committee member to have a greater impact and participate to the decision process. You would need to be voted in as a director. The agent acts for the OMC. As for the issues you might have raised, the agent might want the authorisation of the OMC to address them or the OMC might not have communicated them to the agent. Or, as you speak about your bill, the work necessary might be too expensive and the OMC might be short in terms of budget as generally requests would have a cost.
