Oliver B, Please check out this site. It gives you the details etc. Is the Administrator a member of the administrator & Fincas. ( The body that look after and sets are practise standards etc, each province has its own)
Have you taken the matter with the President of your community ? It is his an responsibilty to provide all that you have asked for and like all the services he has delegated to the administrator. What are the views of the other residents, have you attended a meeting or used a proxy ?
Depending on your circumstances you can place your service charges with a Notary until the matter has been resolved.
