jeff – if your former Strata Manager was not the Licensee of the business, then you or your Owners Corporation should make contact with whoever is, and explain the situation.
Depending upon how that goes, there is a Code of Conduct under the NSW Property, Stock and Business Agents Act (2010) that’s enforced by the NSW Department of Fair Trading (DFT), and another administered by Strata Community Australia (SCA) as the peak industry association.
So again depending upon the reaction that you get from the Licensee, I’d suggest that you read through THIS document and then contact SCA in the first instance to ascertain if your Strata Manager (or their Agency) is a Member, and if so then you or your Owners Corporation (O/C) can lodge a Complaint.
If your former Strata Manager is not an SCA Member (or even of they are), then you or your O/C can lodge a Complaint on-line with the DFT.
