Location Sign for Strata Complex

The entrance for our main driveway is different to the actual address. (Strange I know!)  Our visitors’ car park and letterboxes are at this address.  I asked six months ago for the location sign to be replaced as it had either rotted or was vandalised.  Tradespeople are having difficulty finding the main entrance.  I indicated to the Managing Agents that valuable time could be wasted if a resident required an emergency vehicle (Police, ambulance, fire brigade).  They passed on my request to the EC and again, silence.  We are financial at present – so that’s not the problem.  When I was on the EC, I was informed that any safety issue such as this needed to be attended to as our EC had a ‘personal legal liability’.  This could lead to the EC being sued as they knew of the problem and didn’t act.  Any ideas???
