It’s funny how just about everybody involved in strata thinks there should be a Strata Ombudsman … except for the government. The fact is that if they had one, he or she would be swamped with complaints – many valid, some less so – from day one.
To answer your question, Strata Managers come under the Stock and Property Agents laws and as such complaints have to be made through Fair Trading.
Do this as a matter or urgency before this firm disappears up its own off-the-shelf shell company and sells its business and data base to someone else.
