I would call a meeting of the EC, very formally, by the book etc. Pass resolutions and record minutes etc that the managing agent be required to provide copies of the decision to repair carports (since you can't find it in minutes), to disclose any other costs that might be pending etc. Meanwhile talk to the manager and make it clear you do not appreciate being kept in the dark, that you take your responsibilities seriously and so on. I'd show the manager you mean business and he/she should fall into line. If not, then think about appointing a new manager.
