If you like the strata company but dislike the person allocated by the strata company to manage your scheme (i.e. your strata manager) then why don’t you contact the strata company and raise your concerns? Your strata company may be unaware that their staff (i.e.your strata manager) are not performing to the satisfaction of their clients (i.e. your scheme). Your strata company may be happy to allocate a different strata manager to your scheme rather than lose your business.
