A startling fact to realize is that your Strata Manager comes without need for any level of industry training or minimum understanding of compliance, nor is registered. The company itself might have the usual insurances but the person assigned to your account needs very little in the way of formal training. Industry accreditation is a option but is not a requirement.
Hence the number of issues such as you mention comes with very little recourse other than owners personally knowing the law and the requirements and ensuring these are followed. Left up to the Strata dude you can end up with issues such as you have. Firstly, they look after themself, then, the pander to the committee, then you might get a look in if the first two don’t get in the way or you stand your ground.
Sorry to hear this, but it’s not unusual.
