A strata manager can only be dismissed by a majority vote of the OC at a general meeting or through applying for a compulsory managing agent under s162 of the SSMA through the NCAT. One owner cannot dismiss a Strata Agent if they are not the majority regardless of how bad the managing agent is. Also the buck lies with the OC not the strata manager here, yes the strata manager may be providing poor customer service, but if that is the case, the Owners need to step up and take some action. If the other owners are against you, then mediation and adjudication is usually the next step in the process.
